for one year, off and on, I have been experiencing cramps of the femoral nerve. The pain is incredible when a big cramp attacks. It is not in the muscle. That is when I was told it was an inflammed femoral nerve and was prescribed prednisone and though the severity of the cramps lessened, they are begining to return and gradually increasing in pain and frequency. Massage, heat, stretching and 'Tens' units do not seem to give relief. I wear a lumbar brace quite often and wonder if it could be responsible. If the brace is not the cause, what causes the nerve to cramp and what can I expect as a remedy?
