Pichuu-
Please do give the Cymbalta a try. There are many people on the boards who get GREAT relief for their nerve pain from it. You may find this is something that your doctor will have to titrate your dose up to a good level to bring your pain down, so be patient.
Keep checking back, because someone will see your post and give you some more concrete information about Cymbalta and the benefit they get from it. I'm not saying that because it works great for them it will for you, but I am hoping it will be a good match for you.
Good Luck!
