Thank you for your replies. They have been very helpful. I intend to visit a physiotherapist to hopefully reverse this muscle problem.

One very obvious symptom that I should have mentioned is that the muscle between the bottom of my rib cage and top of my pelvis is so weak on my right side that the bones are nearly touching. The left side does not have this problem. My nerve injury was on my right lower extremity.

Thanks again for all your help.
