Treating Muscle Soreness After Exercise
Medical and fitness professionals call sore muscles after exercise delayed onset muscle soreness, or DOMS. It's a common complaint of many athletes, but also of anyone who puts their muscles to greater use than is typical for them. The condition stems from exercise-induced muscle damage, or inflammation of the muscle as a result of microtears of muscle fibers. Many treatment options exist for muscle pain relief.
