Well I am on Cymbalta,Serequil,Neurontin,klonopin. I have been weaning off the dose because I am not feeling any benefits mind or body. Everyone is different.
Have you tried elavil? When I was having a hard time with meds I tried that one. Also for me for ex when I first tried neurontin I had a hard time with it but the dose was too hgih to start and also the side effects lessened after a few days.
Sorry I don't have more advice. Have you seen a pain doctor? I would because they work better with pain control then neurologists or gp I feel.
