While getting my last physical my dr said i had minor scoliosis. He gave me some stretches to do and said it was probably from playing tennis wheremy back muscles on the right side of my body had become stronger an pushed over slightly. I really havent been doing any sort of special stretches but after tennis my back does seem to hurt. Not excruciating pain but rather a minor annoyance. Is this nothing to worry about? I really dont want to get injured but i dont know how to prevent back injury.
