Calf Strain Physiotherapy
Calf pain can make pushing off, climbing stairs and returning to running difficult. Rehabilitation should build walking and calf strength without overlooking other causes of pain.
A calf strain involves one of the muscles behind the lower leg, often after a forceful push-off or landing. It is not the same as Achilles tendon pain, and unexplained calf swelling must not automatically be labelled a strain. At our Newham clinic in Plaistow, assessment considers the event, ankle movement and your walking. Possible blood-clot symptoms require urgent medical care, not massage or an exercise trial.
This guide is general information and does not replace a clinical assessment.
When to get urgent help
Unexplained one-sided calf pain with swelling, warmth or skin colour changes needs urgent GP or NHS 111 assessment for a possible blood clot. If you also have breathlessness or chest pain, call 999. Do not massage or exercise the calf while waiting for assessment.

Common Symptoms
Sudden pain or a pulling sensation at the back of the lower leg.
Local soreness, swelling or bruising after an identifiable injury.
Difficulty placing the heel down or pushing through the toes when walking.

Seek Prompt Medical Advice If You Have
Call 999 or go to A&E immediately for leg pain and swelling with chest pain or breathlessness.
Ask for an urgent GP appointment or contact NHS 111 for new one-sided calf swelling, warmth or skin-colour change, especially without a clear injury.
Contact NHS 111 now if you suddenly cannot push off or walk after a snap; do not assume this is a minor strain.
Contact NHS 111 for severe worsening pain, major swelling or fever rather than waiting for a routine appointment.
If you are unsure, call NHS 111 or seek urgent medical care.
Assessment
Review how pain began and screen unexplained swelling for urgent medical concerns.
Examine comfortable ankle movement, calf tenderness and walking pattern.
Assess calf function at a level appropriate to the injury stage.
Discuss standing, commuting and sporting demands to set practical rehabilitation checkpoints.
Treatment
Adjust walking and standing demands while rebuilding comfortable ankle movement.
Progress calf strengthening from a manageable starting point, using your response to guide changes.
Add balance, landing and running preparation when strength and walking allow.
Review work or sport goals so the plan extends beyond pain settling at rest.
Aftercare & self-management
At your appointment, agree which exercises to do, how often to practise them and when to review your progress.
Choose supportive footwear and avoid forcing a painful calf stretch in the early stage.
Break walking into comfortable distances rather than limping through a long outing.
Avoid vigorous massage or heat over a fresh swollen injury.
Note any lasting increase in swelling after activity and discuss it before progressing.
Frequently Asked Questions
Could calf pain be a blood clot rather than a strain?+
Yes. A clot can cause one-sided pain and swelling, sometimes without an obvious trigger. Get urgent medical advice; physiotherapy cannot safely rule it out online.
When is running appropriate again?+
Start with comfortable walking, movement and strength, then progress through impact tasks. Your plan should reflect running demands, not simply how many days have passed.
Is it useful to keep stretching a sore calf?+
Forcing a painful stretch can irritate a fresh strain. Gentle movement and later strengthening may be more appropriate; the assessment helps identify a suitable starting point.
What should I bring to my appointment?+
Bring any previous assessment information and describe the activity you want to return to. Tell us about recent surgery, travel or changes in swelling before starting a routine rehabilitation visit.
