When I Was Doing Warm-ups For Volleyball Practice, I Did

When I was doing warm-ups for volleyball practice, I did something to my leg. I was trying to stretch my legs as far as I could and when I shifted my weight from side to side, I got bad pains in my thighs. I either over stretched it or I stressed my thigh muscles. Whenever I try to bend I get bad pains and I can barely stand up. I've tried massaging because I've been known to get knotted muscles. But it's really painful and I've been doing it often. I also got a heat pad, iced my thighs, and now I'm wearing different braces. I don't know if it's temporally gonna be in pain or I messed up my leg.
