I was squatting 405 and right at the bottom of the squat I felt 2 slight pops right where the hamstring meets the butt (it is right around where the bottom of my left pants pocket would be). I feel like I have been kicked in the butt right there. The night of, which is right now, I feel a low throbbing pain in the same area and the spot is soar to the touch. I'm not sure if this is a tendon that popped or what. Is there anyone who could advise me on this injury and tell me maybe what it might be or what the recovery time might be. Also will an injury like this need immediate attention or not and will it recover %100?
