Felt multiple crackles/pops(and I thought I heard it as well) while doing a left front split. I thought maybe it was my hip popping, because at first I was not in pain. Now my hamstring has a dull ache that continues into my hip...and is stiff. And...I did not actually feel the crackle/pop sensation eminating from my hip...it was around the area where the muscle connects to the bone. I can walk though. What do you think has happened? Muscle tear? I have been resting, icing, and compressing it. Would love to get back to exercising as soon as possible.
