Key takeaway
Pain at the back of the heel deserves an assessment that distinguishes gradual tendon symptoms from a sudden injury. A possible Achilles rupture needs urgent medical care, not a trial of home exercises.
Start with how the pain began
Perhaps your heel feels stiff when you first get moving, or the back of your ankle aches after a longer walk. Achilles tendinopathy can cause pain, stiffness and swelling in this area, sometimes easing as you move before becoming troublesome again after activity. NHS: Achilles tendinopathy
The Achilles tendon connects your calf muscles to your heel. It helps you push off during walking, climb stairs and rise onto your toes. Symptoms may develop after a substantial increase in activity, but the location of pain alone cannot confirm the cause. AAOS: Achilles tendinitis
A sudden pop needs prompt attention
Seek urgent medical assessment if you feel a sudden snap or pop, feel as though someone kicked the back of your calf, or develop new difficulty pushing off or walking after an injury. These can be signs of an Achilles rupture.
Pain can settle after a rupture, and some people can still walk flat-footed. Improvement in pain does not rule out a tear. Stop the activity and get checked rather than testing the tendon repeatedly or trying to stretch through it. Do not wait for a routine rehabilitation appointment.

New, unexplained one-sided calf pain and swelling also need urgent medical attention because a blood clot is one possible cause. If these symptoms occur with chest pain or shortness of breath, call 911. NHS: Deep vein thrombosis
Where the pain sits matters
Achilles symptoms can involve the middle of the tendon above the heel or the point where it attaches to the heel bone. Clinicians call these midportion and insertional tendinopathy. The distinction matters when choosing exercises.
For example, lowering your heel below a step is not a suitable starting exercise for every painful Achilles. AAOS specifically cautions against that heel-drop exercise for insertional symptoms. Avoid copying an exercise routine before the problem and appropriate movement range are clear. AAOS: Achilles tendinitis
What an assessment can clarify
An examination considers when symptoms began, recent activity changes, tenderness, swelling and ankle movement. Imaging may help in selected situations, but an MRI is not automatically necessary for Achilles tendinopathy. AAOS: Achilles tendinitis
Tell your clinician about your health conditions, medications and any sudden injury. Those details can affect the assessment. Bring a clear description of what has become difficult, whether that is walking at work, taking stairs or returning to a sport. AAOS: Achilles tendon rupture
Adjust activity, then rebuild capacity
Once an assessment supports midportion Achilles tendinopathy and excludes a more urgent injury, complete rest is generally not the goal. The 2024 physical therapy guideline recommends continuing suitable activity within pain tolerance and using tendon-loading exercise as a first-line treatment.
Loading means asking the calf and tendon to work against resistance. The starting exercise, effort and progression should match the person’s symptoms and ability. A sudden injury or pain at the heel attachment may require a different approach; this guideline is specifically about midportion tendinopathy. 2024 midportion Achilles tendinopathy clinical practice guideline
A useful question is, “What can I keep doing, and what should I temporarily change?” Your clinician can help adjust activity and an exercise plan rather than leaving you to choose between doing nothing and pushing through everything.
Track everyday progress
Notice how the tendon responds during activity and afterward. Tell your clinician if symptoms remain more aggravated the next day or ordinary walking is getting harder. Rehabilitation needs adjustment when the challenge exceeds what you can currently manage. Improvement often takes months, so discuss realistic goals rather than expecting a fixed recovery date.
