I know exactly how you feel. I had developed serious knee problems due to sports injuries in school and was left with plenty of pain and discomfort. I have been successfully treated by my orthopaedist and an anaesthesiologist through the use of what they refer to as a sympathetic nerve block. They block the nerve using a spinal nerve block. The last time I had it done was almost ten years ago and it's made a big difference. Don't give up hope!
