How do I know if it is a calf strain or a blood clot?

A strain has a moment you can name, usually during exercise, and hurts when you stretch or contract the muscle. A deep vein thrombosis tends to come on without an injury, with a calf that is swollen, warm, tender and painful to walk on, often after a flight, surgery, illness or pregnancy. That needs urgent medical assessment, not massage. With breathlessness or chest pain, call 999.

When can I run again after a hamstring strain?

When the leg can do the job, not when the calendar says so. The usual markers are full pain-free range of movement, strength close to the other side, and a step-by-step progression through jogging, striding and then sprinting without symptoms the next day. A mild strain often reaches steady running in two to four weeks, with sprinting several weeks after that.

Should I stretch a strained muscle?

Not hard, and not early. Aggressive stretching of a fresh tear tends to keep it irritable. Gentle movement within comfort in the first days is fine and helpful. After that, the useful work is progressive loading, which includes controlled exercise at longer muscle lengths as things settle. That builds tolerance in a way passive stretching does not.

Hamstring and Calf Strain Treatment in Bromley

A strain is a muscle pulled beyond what its fibres could take, so some of them tear. In the hamstrings, at the back of the thigh, it usually happens at speed or with the leg stretched out in front. In the calf it tends to happen on push-off, and people often describe being kicked in the back of the leg and turning round to see who did it.

Our Bromley clinic sees a lot of these from Saturday football, tennis and five-a-side, and from people who sprinted for a train at Shortlands without warming up. Calf strains cluster in the over-forties who have taken up racket sports again. Two patterns stand out: people often arrive wanting deep work on a muscle far too fresh for it, and those who re-tear are the ones who went back on how it felt rather than what it could do.

How to tell if that is what you have

A sudden onset you can pin to a moment, sometimes with a pop or snap.
Tenderness over a defined patch of muscle, with pain on stretching it and on contracting against resistance.
Bruising appearing a day or two later, often tracking down the leg.
A limp, and difficulty pushing off or accelerating.
In a severe tear, immediate inability to weight-bear, sometimes with a visible dent or gap.

Not everything at the back of the leg is a strain. A gradual deep ache at the sitting bone, worse with sitting and driving, is more likely a high hamstring tendon problem. Pins and needles suggest the lower back. A sudden pop at the back of the ankle with no push-off can be a ruptured Achilles. And a calf that is swollen, hot and tender without a clear injury must be treated as a possible blood clot until a doctor says otherwise.

What actually causes it

The muscle is asked to produce more force than it can handle, usually while lengthening under load — as the leg swings forward before the foot lands, or as you change direction. Fatigue makes it likelier, which is why so many happen late in a game.

The single biggest risk factor is having had a strain before, particularly one that was rushed back. Add cold starts, little recent fast running, and strength that falls away at long muscle lengths, and the ingredients are there.

How we treat it at the clinic

Timing matters. For the first few days a fresh tear wants relative rest and gentle pain-free movement, not vigorous hands-on treatment. We can assess you early and start treatment when the tissue is ready.

What determines the outcome is a structured exercise programme: early isometric holds, progressive loading into longer muscle lengths, then a graded running build-up with criteria for each stage. That evidence is strong. Once the acute phase passes, sports massage around — not directly on — the injury helps with the protective tightening that spreads through the leg.

What you can do yourself

In the first two or three days keep walking within comfort, use a compression sleeve if it helps, and do not stretch into pain.
Start loading gently and early. Pain-free isometric holds, then slow controlled work, beats waiting for the pain to disappear.
Use criteria, not the calendar: full pain-free range, near-equal strength side to side, and a progression through jogging, striding and sprinting before match pace.
Keep the programme going for six weeks after you feel fine; that window is when re-tears happen.

How long it takes

A mild hamstring strain is usually back to steady running in two to four weeks and sprinting in six or more. A moderate one runs to six to twelve weeks. Calf strains behave similarly, though an injury to the deeper soleus muscle is often slower, and the over-forties should expect the longer end.

A complete tear, or one where the tendon attaches to the pelvis, needs a surgical opinion rather than a waiting game.

When to see a doctor instead

A pop with immediate inability to weight-bear, an obvious gap in the muscle, or a large bruise high in the back of the thigh. That can be a complete tear or a tendon pulled off the bone, and needs same-day medical assessment.
A calf that is swollen, hot and tender with pain on walking, particularly after a flight, surgery, immobility or pregnancy. That can be a deep vein thrombosis, which needs urgent medical assessment through your GP, 111 or A and E, and must not be massaged. With breathlessness or chest pain, call 999.
A sudden pop at the back of the ankle with no ability to rise onto the toes, which may be a ruptured Achilles tendon.
Numbness, pins and needles, or back pain travelling down the leg.
No improvement after two to three weeks, or the same muscle going repeatedly.
