Hi there! I am no dr but I do know that some medications such as cymbalta is not just used for depression but it also has norepenephrine(sp) and serotonin which also helps with pain just like some depression meds help anxiety and bipolar. Maybe I can eplain it better by saying that some meds are used for more than one thing, maybe that may explain it better. I too have fibromyalgia along with other medical problems and their are times that it is difficult to explain things, I call it fibro-fog.
I have always learned that when a Dr. Prescibes a new med for me that I do some research on it. I have also leaned that it can take sometimes two weeks to two months for meds such as that to do what they are supposed to do.

The very best to you!
