Mine was sort of self-diagnosed. Left side chest pain with sensitivity to touch. Numbness and tingling in lower legs and feet. Also a terrible itch all over which got worse overnight. Was taking GabaPentin at the time, but it was useless. While recovering from lumbar surgery, the hospitalist switched me over to PreGabalin which helped immensely. My pain doc was apprhensive about PreGabalin and would have recommended Cymbalta. He did offer Baclofen, but I couldn't tolerate it and the PreGabalin at the same time.
