I am truly sorry to hear that you have been having back problems. They definitely are a (no pun intended) Pain in the back side. I hurt my back in Feb, of 2000 and I always have pain also. I damaged 3 disc in my lower back, and am always feeling pain, but I got used to it, so it doesn't totally run my life, thank God. On occasion I feel it down into my left thigh. Usually though it is only in my tail bone and hip area. So I know how you feel, and hope that you find something that works for you in alleviating your pain.
