Hi, I am an overweight teenager and I havenâ??t exercise in a long while, and this morning I wnet for a two mile walk and before I reached a mile, the part where my left thig is connected to my upper body just below my buttocks started paining. And I was walking at a pretty fast pace from the start. And now everytime I walk or make a step it pains and it feels like its coming out of a socket and going back in. Unfortunately I do not know much about the body so I want to know if u can tell me or suggest to me what u think is damage because I have a doubt that itâ??s a muscle beacause normally when a musle pulls in my body it feels different. Can u please tell me what you think is the problem?
