I was taking Cymbalta, did not work. So I was given gabapentin and tramadol, those did not work. Was given muscle relaxers, and low dose Zongran. Was not working. Now I am currently taking a stronger dose Zongran of 50mg and steroids. It's not working. I already had a left Lumbar Sympathetic Nerve Block. Did not work, made my CRPS worse. Have to get a different Nerve Block. I am so lost and in pain .
