Im having a muscle pain, what do i need to do?

It depends.: Musle pain is by far usually NOT a serious condition and most often represents excessive use or overuse of a muscle beyond its normal capacity. Short term treatment should include rest, ice/heat, and/or over the counter anti inflammatory medications, and possibly very gentle stretches when ready. Muscle pain which persists beyond 2-3 weeks, should be evaluated by an appropriately trained provider
