When Should You Worry About Calf Pain? (and What to Do Next)
Calf muscle pain is common and can be severe, even if the underlying cause is benign (harmless) and reversible, like an exercise-associated muscle cramp or strain. In some cases, though, calf pain is a sign of a serious health problem, like nerve damage, narrowing of blood vessels, or a blood clot deep within a lower leg vein—called deep venous thrombosis.
