Ouch! I can relate too. I tore my hamstring in three spots at yoga! It hurt so bad and bled all the way from the top of the thigh to the back of my knee under the skin. I went to sports physio, did the rest, ice, compression, and it took months to be able to extend my leg fully. Just make sure you follow the advice to a T for quicker healing, and rest... So important. Baby that leg! Hope it gets better soon and nothing to serious .
