During my first set of warmup squats I noticed a sharp pain in my right thigh. It would happen when I was on my way down, but fine on the way up. By the time I got to my 3rd set, I almost lost control of the bar and let it drop because the pain kind of spiked (It was a shooting pain). I put the bar back, and tried to stretch a bit.
I'm not sure what this is. It felt fine before squats, and it feels fine now. It's only in my right thigh. Not sure whats going on.
