I have had 2 lower lumbar laminectomies. I have Fibromlyalgia and Arthritis. When I lie on either side, my hips have pain. I also experience pain in my groin area, and from the surgery sites which are located between the 4th and 5th disc. Upon rising from a sitting position, I am in such pain that I have to stand still for a moment prior to moving. I have been given the latest medication which is Nucynta 10 mgs. to take for this but to no avail. I use a TENS unit, as well.
you get the pain because you have fibromyalgia. I'm not trying to be "cute" but that's the answer. Of course the surgeries you have had are not helping either. Strengethen your legs and your "core" muscles and you will find things easier. When you walk hold your chest up and suck in that belly, don't hold your breath though. As far as pain when you lie on your side, I just purchased a generic memory foam matress topper and it is wonderful. I have the same hip/leg/shoulder problem, mostly hips. I haven't had the surgery yet, they need to do my neck also. I'm putting it off as long as I can. Don't know if any of this helps but hope so. Keep you in my prayers. Have a wonderful New Year!
