Hey guys, I just came across my second serious tennis injury. Shoulder pain. Here's the bio on me. 17 Years old, tall, thin, been playing almost a year, SW Grip, One handed backhand. Well I just got my ball machine in a week ago and I took it for a hit. Also when coming out I though to used a closed stance on my forheands and point my racquet butt at the ball. I was hitting as hard as I could, and then I got a high ball that I swung down on. Then came a slight pain. As I continued to fight through the pain it only grew. I decided to call it a day and hope better next time. After 5 minutes the injury flared back up today. Forehands and serve's were very painful. Here is a picture of where my injury is. http://pain.health-info.org/Pain Pages/shoulder.htm The second picture, around the bottom outside of the shoulder blade, or what ever those to bones are that stick out of your back. So my questions are if you can answer them What kind of injury is this? Should I see the doctor? Would lifting weights solve this? How long will this keep me out? I appreciate any attempt of an helpful answer very much. Please answer ASAP cause I really want to go play tennis! Deuces!
