Hi, I was diagnosed with moderately severe spinal stenosis in the area of the 4th and fifth lumbar vertabre. I also have a fused 5th lumbar and sacral area. I was born with that, I mean. Besides the pain in the back and legs in general, I am having toruble with my right knee. Now I have had problems with the knee a long time. About a year ago I had it exrayed and there was water on the knee and arthritis, I went to see the doctor and she suspected a torn miniscus. I gradually got better. Now the pain is totally different, and I am wondering if the back problems have anything to do with it. I will be walking around and suddenly it will have sharp pains and I can barely bear weight on it. Other times I cant straighten it due to pain, I had to take my hands and straighten it. The pain with the first injury was constant. No difference in back pain, it hurts a lot when I first get up, and when I stand or walk. In between drs right now due to move.
