Calf pain can result from many different causes. Sometimes something as simple as over-activity causes muscle strain in the calf. Or, dietary imbalances may cause cramping in the calf.
However, calf pain may be a symptom of more serious problems as well. Poor blood flow to the legs (peripheral vascular disease, or PVD) may cause cramping in the calf while walking or when sitting with the legs elevated. A blood clot in the calf (deep vein thrombosis or DVT), a very serious problem, also produces pain in the calf.
Calf pain can also be the result of injuries, such as tearing of the calf muscle or tendonitis. In any case, it is not something that should be ignored. A foot and ankle surgeon should be seen for a thorough examination and diagnosis, to determine whether the cause is due to a serious health problem, an injury, or merely overuse. The cause of the calf pain will determine the proper treatment.
