Started having tight hamstrings and calves which lead to major right knee pain. When standing for long periods or sitting to drive a truck, causes a nerve to begin acting up in my butt, hip, down the outside of my leg to the backside of my knee causing intense pain in the knee. Hamstring gets very tight along with my calve. When driving and moving my rigt foot around to drive makes outside area of my knee hurt badly. If you rub this area it gets even worse. MRI on knee and lower lumbar. Both Dr's said everything looks good. Rheumotologist said i had no arthritis so now im lost and needing you folks to help me out. I have lost some range of motion in right knee and left leg is starting to tighten up and hurt as well. Cant keep going on like this daily. If you have had any symptoms like this, what did you find out. Lost and depressed with quality of life going downhill fast.
