Chronic exertional compartment syndrome is an exercise-induced condition in which the pressure in the muscles increases to extreme levels during exercise. The pressure creates a decrease in blood flow to the affected area which leads to a deprivation of oxygen to the muscles.[2] The symptoms are a sensation of extreme tightness in the affected muscles followed by a burning sensation if exercise is continued. Chronic exertional compartment syndrome usually occurs in athletes who participate in repetitive impact sports such as running.
