I had a TKR on my left knee on Feb of 2012. I had been in constant pain before that but seemed better after it finally healed. Then the back and hip pain started. Went to regular doctor and we tried muscle relaxers and pain meds, but no help so the years rocked on and then after X-rays doctor said I had scoliosis. I said I have never had that!! Sent me to PT and we tried that but no help. I had an appointment with podiatry dr and mentioned back pain, he sent me to orthotic dr and after looking at tests, X-rays, scans etc he said here is your problem!!! You left leg is 3/4 in shorter that right leg. So we started with 1/2 in orthotics for a year and finally got to 3/4 in and my muscle back pain is so much better but I have to wear them consistently. But my lower back pain and hip pain from scoliosis is there all the time. Sometimes worse than others. So I guess I live with chronic back pain for the rest of my life. Does not seem fair…
