I have disc herniation in T6 and T7. I also suffered severe knee pain and ankle swelling. X-rays showed osteoarthritis in the knee. I want to a chiro several times and found relief. We had a lot of snow and shoveled a deck throwing the snow over the railing. Bang, the knee pain returned. My regular doctor said it can't be from the back because my whole leg isn't affected. Has anyone else had a similar problem?
