How do you know whether scar tissue has built up? Right now i have full range of motion in stretching, pain when stretching, its only when i contract the hamstring, it isnt painful but i can actually feel the whole hamstring squeezing together, it isnt so with the uninjured leg. Most times when im in a crouched position eg squat position if i contract it i feel it.
It's an irritating feeling, cause it feels as if it needs to be hurt(deep tissue/punched) to stop feeling like that.
