Hi i have been diagnosed with sacroillitis, after a back injury 5yrs ago. A year and a half ago i was diagnosed with hip bursitis. Over the last year, i have been having increasing pain in my knees, legs and feet. The combination of these has left me in constant pain and virtually housebound. I am 43 and was medically retired at 41, as i could no longer cope. I am on duragesic fentanyl patches, 25mg and 12mg, but i am getting no relief at all. I get injections in back and hips, but this time round got no relief at all. I was very active before my back injury, which isn't quite as painful as my hips and legs. My consultant at pain clinic said knee, leg and feet pain was connected to my back, but he had no time to discuss it!!! I was wondering if anyone else has a combination of these problems? Life is hard and very painful!!!
