Ive been having bad pains in my right side. i am 15 and in school i would walk around and i would notice the pain would get worse as i was more active. I just figured that the back pain was from my bookbag. its just keeps getting worse i am no longer in school becuz the pain in constant and it gets worse the more active i am. ive been to the doctors and they dont kno what it is. I have to go in for an exploratory surgery. does anyone know what this might be?
