Hi myeamans, I am probably not the best person to give advise, If you post this as a new post their are a lot of people who will be able to give you a lot of advise. I have only been on the cymbalta myself for a month also, my doctor said to give it three months as that is how long it takes to work properly, as I said my back feels a lot better now, regarding burning feet, a lot of people have sugested a product called biofreeze it is available in the US but is hard to get in Australia where I live.
hope this is of some help, it seems this is a long and difficult disorder to get over if you ever do.
Best Wishes

Lesley
