How to know if you tore your hamstring or just had a strain? i was sprinting when i heard my hamstring pop. the pain wasn't too bad but i wasn't able to continue running. walking is hard but manageable. i had a different injury a week prior?

When an injured patient describes a "pop", the doctor will often ask: "Did you feel a pop or hear a pop?" When we strain or tear a muscle we feel the pop and then pain. When a tendon ruptures it creates an audible snapping sound. Tendons have minimal nerve innervation, so we often don't feel much but lose function of the detached muscle. This is a serious injury. See an orthopedist NOW.
