shoulder problems

My shoulder problems started when I was in 5th grade. I was carrying a really heavy backpack on my right shoulder. It popped out and I screamed due to the pain. I went to a private school, so there were an ample emount of doctors around. One of them came over and relocated my shoulder. Ever since then, it pops out every once in a while and I pop it back. During the past several months, it's dislocated anywhere from two to six times daily! This past week, it is permanently out. It hurts to move even the slightest bit. The pain makes me dizzy and feel very sick. Luckily, I am going to see a doctor on Thursday. Hopefully they find a problem that is easily corrected.
