I did my split on my right leg and pushed a little bit further down for my tryouts . At first I didnt really feel pain until I had gotten home or really the next day .  Does heating pads work? how long will it take to heal? it feels like slight pain but still hurts .
Rather than using heating pad , you should sit in a tub with gentle warm water filled in it. This is called sitz bath. This is best for such injuries. Also take voveron tablet and rest. This injury will take at least one week for healing.
