MORE INFO:
Delayed-onset muscle soreness (DOMS) is muscle pain that begins after you’ve worked out. It normally starts a day or two after a workout. You won’t feel DOMS during a workout.
Pain felt during or immediately after a workout is a different kind of muscle soreness. It’s called acute muscle soreness.
Acute muscle soreness is that burning sensation you feel in a muscle during a workout due to a quick buildup of the buildup of metabolites during intense exercise. It usually disappears as soon as or shortly after you stop exercising.
