Hi, I hit the outer thigh (almost at the back of my leg) on my right leg on a stationary carriage today while playing table tennis at work. Immediately it happened I felt a great deal of pain but shook it off and kept on playing. After the game I applied a muscle rub on it and Its been over 2 hours since I hit it and I still feel a lot of pain on that leg. I am able to walk without a noticeable limp but can still feel the pain in my leg. Should I be worried or is this something that will pass?
