How do I know if my ankle is broken or just sprained?

The Ottawa Ankle Rules give clinicians a reliable way to decide who needs an X-ray -they check for tenderness over specific bony points and the ability to bear weight. [4] If either of those tests is positive, imaging is needed to rule out a fracture. Apply ice and elevation in the meantime, but do not try to self-manage a suspected fracture -have a clinician apply the rules first.

Will my ankle keep giving way after a sprain?

It may, particularly if the sprain was not properly rehabilitated -chronic ankle instability, characterised by recurrent giving way and impaired balance, is a common consequence of under-managed sprains. [3] The good news is that the sensorimotor system that controls ankle stability responds well to retraining: balance and proprioceptive exercises, together with bracing during higher-risk activities, significantly reduce the risk of further episodes. [3, 8]

Why does my heel hurt most in the morning?

Morning first-step pain is the hallmark of plantar fasciitis -it is most noticeable with weight-bearing after any period of inactivity. [2] For most people it is worst with those first steps out of bed, eases after 10 to 15 minutes of movement, then returns after a long day on the feet. The same pain-after-rest pattern often reappears mid-day after sitting for a while.

Can I keep exercising with Achilles or plantar fascia pain?

In most cases yes, with modifications. For Achilles tendinopathy, the guideline-directed treatment actively includes continued activity -loading the tendon through exercise is the therapy, not a risk to it. [5] For plantar fasciitis, lower-impact activities like swimming or cycling are easier to continue while you work through the stretching and footwear changes; a physiotherapist can advise on what is safe for your specific presentation and load level.

Do I need custom orthotics for foot pain?

Not necessarily as a first step. Current clinical guidelines state that orthoses should not be used as a standalone or first-line treatment for plantar fasciitis -stretching, taping, and manual therapy have stronger evidence at first presentation. [2] For posterior tibial tendon dysfunction (flat foot), personalised arch-support orthoses combined with exercise show more consistent benefit, but whether orthoses are appropriate for you depends on individual assessment findings. [7]

Key Facts

✔ Foot and ankle pain affects approximately one in five people -risk factors include increasing age, female gender, and obesity -and several very different conditions can produce symptoms that feel almost identical. [1]
✔ Where the pain sits is the most important distinguishing feature: plantar fasciitis causes pain at the inner edge of the heel; Achilles tendinopathy causes pain 2-6 cm above the heel; lateral ankle sprains cause pain and swelling on the outside of the ankle. [2, 5, 3]
✔ For plantar fasciitis, first-line treatment includes stretching, taping, and manual therapy (all Grade A evidence) - orthoses are not recommended as a standalone first treatment. [2]
✔ For midportion Achilles tendinopathy, progressive mechanical loading exercise is the first-line treatment (Grade A) - complete rest is specifically not recommended; continuing activity within pain tolerance is advised. [5]
✔ After an ankle injury, the Ottawa Ankle Rules - checking for bony tenderness and ability to bear weight -identify who needs an X-ray, with a pooled sensitivity above 99% for detecting fractures. [4]

30-Second Summary

Most foot and ankle conditions have a distinctive pain pattern -where it hurts, when it is worst, and what triggers it -and matching that pattern to the right diagnosis is the first step to the right treatment. For plantar fasciitis and Achilles tendinopathy, the treatment approach is specific and evidence-based; for ankle sprains, the real risk is under-management and chronic instability. If you cannot bear weight after an ankle injury, heard a pop at the heel, or have visible deformity, seek same-day urgent assessment before anything else.

Introduction

Your feet and ankles work hard -absorbing impact, adapting to uneven ground, and driving you through every step. When something goes wrong, the pain can stop you quickly. But foot and ankle pain is rarely as simple as it looks: plantar fasciitis, Achilles tendinopathy, and an ankle sprain can all cause heel pain, and each one calls for a completely different response. Getting the right answer starts with reading the right signals.
This article maps the most common foot and ankle conditions to the symptoms that distinguish them. It covers plantar fasciitis, Achilles tendinopathy, posterior tibial tendon dysfunction, lateral ankle sprains, and chronic ankle instability -explaining what causes each one, what treatment involves, and what you can do now. It also explains when pain warrants urgent assessment and when a structured physiotherapy program is the right next step.

What Is Foot and Ankle Pain?

Foot and ankle pain is not a single condition -it is a symptom that can arise from tendons, ligaments, fascia, joint surfaces, nerves, and bones. [6] Several of these structures sit close together, share load during movement, and are connected by fascial chains that run the length of the leg. This means that damage or dysfunction in one structure can load adjacent ones and shift where pain is felt.
This is why the location of your pain alone is not enough to diagnose the cause. [6] A clinician will also assess how you walk, how your load shifts through the foot with each step, how much range of motion you have at the ankle, and which specific movements reproduce your pain. That combination of findings, not location alone, is what distinguishes one condition from another.

Causes of Foot and Ankle Pain

Heel Pain: The Most Common Complaint

Heel pain is one of the most common foot and ankle complaints seen in clinical practice, and plantar fasciitis is its most common cause. [1, 2]
The plantar fascia is a thick band of tissue running along the underside of your foot, connecting the heel to the base of the toes. It supports your arch during the push-off phase of walking and running. When repeatedly overloaded, the fascia can develop micro-damage where it attaches to the heel bone. [2]
Common triggers include sudden increases in activity, prolonged standing on hard floors, and limited ankle mobility. Risk factors include limited ankle joint flexibility, a high body mass index in non-athletic individuals, running training loads, and occupations requiring long periods of standing on hard surfaces. [2] A common example is someone who starts a new job requiring eight hours on their feet -within a few weeks, that first painful step out of bed each morning appears.
Achilles tendinopathy produces a different type of heel pain. The Achilles tendon connects the calf muscles to the heel bone -when it is overloaded or given insufficient recovery time, it can develop structural changes that cause pain and stiffness. Midportion Achilles tendinopathy is characterised by pain located approximately 2 to 6 centimetres above where the tendon meets the heel. [5]
This pain begins gradually rather than suddenly and is typically worst with the first steps of the morning or after a period of rest. Pressing directly on the thickened area of the tendon usually reproduces the pain. The annual incidence in recreational runners ranges from 7% to 9%. [5]
Posterior tibial tendon dysfunction - sometimes described as adult-acquired flat foot is a less common but important cause of inner ankle and arch pain. The posterior tibial tendon runs along the inside of the ankle and helps support the arch. When it becomes inflamed or damaged, pain develops along the inside of the foot and ankle, and the arch may gradually flatten over time. [7]

Ankle Pain: Sprains, Instability, and Giving Way

Lateral ankle sprains are the most common injury for which people seek care at emergency departments and sports clinics. [3] A sprain stretches or tears the ligaments on the outside of the ankle typically from a twisting or rolling motion. Despite how routine they appear, fewer than 11% of people who seek care are referred to a rehabilitation specialist within 30 days. [3]
An acute ankle sprain stretches or tears one or more of the ligaments on the outside of the ankle. Pain, swelling, bruising, and difficulty bearing weight are typical immediately after injury. Most people walk away assuming it will heal on its own and while mild sprains often settle, sprains that are not properly rehabilitated carry a significant risk of recurrence. [3, 8]
Among those who seek care for a first-time lateral ankle sprain, around 40% go on to develop chronic ankle instability. [3] This means persistent giving way, recurring sprains, and impaired balance lasting more than 12 months after the original injury.

Other Foot Conditions

Several other conditions cause pain in different parts of the foot. Metatarsalgia produces pain in the ball of the foot; Morton's neuroma causes burning or shooting pain between the toes; tarsal tunnel syndrome produces nerve-related pain and tingling on the inner ankle. All three warrant professional assessment, as their presentations overlap with other diagnoses. [1]
Pain in the foot can also occasionally originate from the spine. The lower back pain causes and symptoms article covers that referred pain pattern in detail.

What the Symptoms Actually Feel Like

Plantar fasciitis produces a sharp, stabbing sensation with the first weight-bearing steps of the morning -typically at the inner edge of the heel. The pain usually eases after 10 to 15 minutes of movement, returns after prolonged time on the feet, and may also flare after sitting for a while during the day. [2] People with plantar fasciitis often live with it for more than a year before seeking treatment, in part because the pain eases once they warm up. [2]
Achilles tendinopathy produces stiffness and aching at the back of the leg, roughly 2 to 6 cm above where the tendon meets the heel. Morning stiffness that eases after a few minutes of movement is a hallmark of this condition. [5] The tendon may also feel thickened or tender to press at the painful point -distinct from plantar fasciitis, which is felt lower, at the inner edge of the heel itself.
Lateral ankle sprain causes immediate pain, swelling, and bruising on the outside of the ankle. Most people can still bear weight on a mild or moderate sprain, though it is painful. Severe sprains may involve significant swelling and difficulty loading the foot at all -the degree of swelling and ability to walk on it are useful indicators of severity. [3]
Chronic ankle instability may produce little pain between episodes, but recurrent giving way, a persistent sensation of weakness, and difficulty with balance and quick direction changes are common. [3] The giving way is typically triggered by uneven ground or sport-specific movements, though it can also occur without a clear reason. Activity limitation and ongoing restriction of participation in sport or exercise are the most common functional consequences. [3]

Treatment Options

For Heel Pain (Plantar Fasciitis)

The 2023 JOSPT clinical practice guidelines recommend several treatments with strong evidence (Grade A). Manual therapy directed at the joints and soft tissues of the leg and foot (the lower extremity) addresses flexibility restrictions and reduces pain. [2] Specific stretching of both the plantar fascia and the calf muscles (gastrocnemius and soleus) produces meaningful reductions in pain in both the short and long term. [2] Foot taping -using rigid or elastic tape -provides short-term relief and functional improvement; physiotherapists typically use it alongside other treatments rather than alone. [2]
Night splints are recommended for people who consistently experience pain with their first step in the morning -a one- to three-month program has strong evidence behind it. [2]
Orthoses (insoles or foot supports) should not be used as a standalone treatment for short-term pain relief, but may be combined with other physiotherapy approaches. [2] A best practice guide synthesising 51 trials and expert and patient input found that core treatment should include taping, stretching, and individualised education. [9] People who do not improve adequately may then benefit from extracorporeal shockwave therapy (ESWT -a non-invasive procedure using acoustic waves), and custom orthoses as a further step if needed. [9]
A 2023 meta-analysis of 236 studies and 15,401 participants found stretching, taping, laser therapy, dry needling, and myofascial release (hands-on soft tissue treatment) all produced meaningful short-term pain reductions. ESWT was the only intervention showing significant benefits across short-, medium-, and long-term outcomes. [10] For a deeper look at Achilles tendinopathy specifically, the RheCore Achilles tendon pain guide covers that condition in full.

For Achilles Tendinopathy

Mechanical loading - performed at least twice weekly within pain tolerance -is the core of treatment. [5] This typically means eccentric exercise (where the calf muscle works as it lengthens) or a heavy-slow-speed program combining both lowering and raising phases. [5] A systematic review of exercise dosing for Achilles tendinopathy found large effect sizes for eccentric loading programs, though the optimal frequency and duration remain an area of ongoing research. [11] Patients continue recreational activity throughout rehabilitation rather than resting -the guideline is explicit that complete rest is not indicated. [5]

For Posterior Tibial Tendon Dysfunction (Flat Foot)

Conservative management focuses on reducing load on the damaged tendon and supporting the arch. A systematic review found that foot orthoses with personalised longitudinal arch support, combined with an exercise program, showed more consistent pain reduction than flat insoles or standard care alone in early-stage posterior tibial tendon dysfunction. [7] The evidence base is limited -the underlying trials were small and frequently at high risk of bias -so individual assessment remains essential to guide the approach. [7]

For Ankle Sprains

Immediately after a lateral ankle sprain, the primary goals are reducing swelling and restoring the ability to bear weight safely. Guidelines recommend using a brace or tape for support and progressively bearing weight from the outset for most sprains. [3] For more severe injuries, brief immobilisation using a semi-rigid brace or boot - up to 10 days-may be appropriate. [3]
After the acute phase, a structured rehabilitation program with active range-of-motion exercises, neuromuscular training (exercises that retrain balance, coordination, and joint position sense), and strength work is essential. [3] Manual therapy - including lymphatic drainage (hands-on techniques to help clear swelling) and ankle joint mobilisation -combined with exercise reduces swelling, improves pain-free mobility, and normalises walking pattern. [3]
For people who have had previous sprains, bracing plus proprioceptive (balance and joint position sense) training is strongly recommended to reduce the risk of reinjury. [3, 8] Evidence for neuromuscular training and external support in preventing recurrent ankle sprains is among the most consistent in the ankle literature. [8]
For those returning to sport after a complex ankle injury or chronic instability, a structured progressive rehabilitation program is recommended. The RheCore sport and performance program page describes the graduated loading, balance work, and sport-specific training that underpins this kind of return-to-activity pathway.

Self-Management

For heel pain, the most consistently evidence-supported thing you can do at home is stretch -both the plantar fascia and the calf. Plantar fascia stretching involves pulling the toes back toward the shin to create tension along the underside of the foot; calf stretching targets the gastrocnemius (knee straight) and soleus (knee slightly bent) separately. [2, 9] Footwear also matters -supportive shoes that allow a small heel-to-toe drop are recommended over flat or thin-soled footwear, particularly during those first minutes after waking. [9]
For Achilles pain, keep moving within what feels manageable -walking, swimming, or cycling are all appropriate. [5] The key home component is progressive calf loading: eccentric heel drops (lowering slowly on the affected leg, raising on both) done at least twice weekly. [5] If you run or train, reduce your volume rather than stopping altogether, and watch for a spike in pain during or after sessions as a signal to ease back.
For posterior tibial tendon dysfunction (inner ankle and arch pain), footwear with supportive arch structure helps reduce the load on the tendon during daily activity. A physiotherapist can advise whether orthoses and a targeted exercise program -the combination that showed the most consistent benefit in the available research -are appropriate for your presentation. [7]
For an acute ankle sprain, elevating the ankle and applying ice in the first 24 to 48 hours can help manage swelling. [1] Start gentle range-of-motion movements (tracing the alphabet with your foot) as soon as they are comfortable -early movement, rather than prolonged rest, produces better outcomes. [8] Begin bearing weight as early as tolerated; if you cannot bear weight at all, this warrants assessment before you manage it at home.

When to See a Physiotherapist

Seek urgent assessment (same day or emergency department) if:

You are completely unable to bear weight after an ankle injury
There is significant deformity or severe swelling at the ankle
You heard or felt a pop and now have severe pain at the back of the heel (possible Achilles tendon rupture)
You have pain directly over the bony points of the ankle or midfoot after an injury - this is a signal to get the Ottawa Ankle Rules applied by a clinician to determine whether imaging is needed [4]

See a physiotherapist when:

Heel or ankle pain has persisted for several weeks despite rest and basic self-care, or keeps returning after it seems to improve
Your ankle regularly gives way, or you have had more than one significant sprain
You have been told you have plantar fasciitis or Achilles tendinopathy but have not had a structured rehabilitation program
Pain is affecting your ability to walk, work, exercise, or sleep
You are returning to sport after an ankle sprain and want to reduce your risk of reinjury

If one or more of those situations applies to you, a clinical assessment can identify the specific structure involved and determine the most appropriate approach -whether that is hands-on treatment, a targeted exercise program, or a combination. The RheCore pain and injury management page describes what this kind of assessment-led physiotherapy covers.

Key Takeaways

Pain location is a starting point, not a diagnosis - the combination of where it hurts, when it is worst, and what triggers it is what points to the right condition and the right treatment. [6]
For plantar fasciitis, start with stretching, taping, and footwear changes; if pain persists beyond several weeks, extracorporeal shockwave therapy is the only intervention with evidence of benefit across short, medium, and long-term outcomes. [9, 10]
Ankle sprains are more serious than most people treat them - fewer than 11% of those who seek care are referred to rehabilitation, and around 40% develop chronic ankle instability; bracing and balance training after a first sprain significantly reduce the risk of a second. [3, 8]
Pain that eases with movement and worsens again with prolonged loading (plantar fasciitis) needs a different approach from pain that builds gradually with cumulative tendon load (Achilles tendinopathy) - matching the intervention to the mechanism is the difference between improvement and stagnation. [2, 5]
PTTD (flat foot pain on the inner ankle and arch) and chronic ankle instability both respond to specific exercise and orthotic programs - neither should be managed with rest alone. [3, 7]
