Hi Hara,
Donna is correct. Prednisone doesn't help Fibro pain, it only makes it worse. The reason is exactly what Donna mentioned. Fibro isn't an inflammatory disorder. So when you add prednisone (cortisol), you have way too much natural and synthetic cortisol in the blood. Excess cortisol actually makes pain worse.
I have to take prednisone for my Lupus. When I'm hurting it's hard sometimes to know if it's from my Lupus or my Fibro. So I do the test.... I increase my prednisone a bit. If I hurt more, then it's actually my Fibro flaring. If I hurt less, then I know it was Lupus and increasing the predisone was the right thing to do.
Definitely talk to your doctor and tell him how you're feeling. I can't understand why in the world they would put you on prednisone for your Fibro. You don't have any inflammatory diseases do you? Let us know how you're doing, okay?
