3. Delayed Muscle Soreness (DOMS)
Just as cramps can be caused by exertion in an exercise routine, pain in the legs can be the result of DOMS or Delayed Muscle Soreness. While cramps are caused by depletion of electrolytes that can be the result of dehydration during exercise, DOMS, as the name suggests, is a delayed reaction to a strenuous exercise routine. DOMS can be triggered by an accumulation of metabolites or strained muscle fibers.
However, these small tears in your muscles are actually a good thing, because they are what leads to the muscles becoming stronger. DOMS may start up to12 hours after the workout was completed and may last for as long as 72 hours.
Ironically, the best way to deal with DOMS is through physical exertion, and also moving around can help ease the pain. You can also deal with the symptoms through applying heat, massaging the area or taking anti-inflammatory medicine.
