Have you seen a back specialist recently? Since you were so young when you had them implanted, would your body have healed enough that you don't need them? I hope this isn't a stupid question but at 17 you were still forming good bone. I was in pain everyday from osteoarthritis and I started taking dehydrolized collagen (Land of Lakes) every day with coffee or fruit juice and I am feeling 95% better...I urge everyone to look into this supplement...it helps with virtual every organ, muscles of our body because our body is made from collagen and we start making less in our 20's...supplementing with this has made a huge difference in my quality of life!
