Cymbalta doesn't work for everyone. That's one of the problems with fibro. What works for one person doesn't necessarily work for the other. Hopefully, with the help of your FM doctor, you will find the right combinations that will help her.
We have had quite a few young people on this forum with fibromyalgia. Many, including our mod Jeannie, have had it since they were toddlers. So, it's unusual but not rare for a teenager to have fibro. We had one girl that was 15 when she started on this forum and is now going to college. It did take many doctor's visits for her to find what worked best for her. So, keep on plugging away. I'm sure she will find relief soon.
