Hello doctor, i'm andrew and my problem is with my middle portion between the chest. The reason for this pain is when I was playing at school in bar rod by the time when I gone up with my hands stretched my friend tickled me so I lost balance and lowered only one hand because3 of that I heard a take sound in my chest and was paining a lot I thought it might go the other day but it didn't. I've consulted many doctors but they said it is just a muscle fibre tear and nothing to worry it will go soon but it didn't. This happened 1 month ago and still I feel pain when giving some stress work to the chest. Please time what to do.
