I am 15 yrs old,
The pain I get is in my upper right back, it is not a constant pain and it only hurts when i move certain ways.
I play football, it is when i get hit from the side or the back when the pain is set off, usually when that happens My back hurts the worse for about 3 days. so bad that i can only either stand up or lay down.
If anyone knows what may cause the pains please reply
