Should fibromyalgia be treated differently in teens vs adults?

Look into cause. Fibromyalgia under age 20 is unusual enough that other diagnoses need to be more carefully ruled out, jra, bone disease, thyroid disorder etc. But if certain of the diagnosis treatment should be basically the same except i would be much more careful using savella (milnacipran) or cymbalta.
Not necessarily. Depends on both degree and kind. Positive health reinforcement with medication secondary.
