When I was young, I used to play high school Volleyball (not that I was any good)
One day during practise I served and felt immediate pain in my shoulder :o
I had dealt with injuries before so just assumed it would get better in a couple of days, because all kids improve right?
Wrong! It didn't get better.....
In fact, my shoulder pain got so bad, I remember lying on my floor crying with a feeling of helplessness because I couldn't even find a comfortable position to lay in.
