DOMS is the muscle soreness that typically appears 12 to 48 hours after unfamiliar or hard exercise, peaking a day or two later. Gentle recovery massage may help tired, sore muscles feel more comfortable, though straight after intense effort lighter work is wiser than deep pressure. It is a normal training response, not an injury, but pain that is sharp, one-sided or lingering well beyond a few days deserves a closer look.
