Hi, Moo Pup. Welcome!
I'm so sorry your sister is going through so much pain....but very glad she has you! There's nothing like someone close to you really being there for you.
There was a time I felt like that - my back pain was absolutely out of control. The worst was after getting an epidural and C-section with my 3rd child. I ended up in the ER one night a few weeks later, certain that my kidneys must be inflammed or I had a serious infection. They gave me a strong painkiller and sent me home.
That was long ago, before I'd even heard of Fibro. I saw so many docs who were dismissive, or downright rude. Even though I didn't like the idea, I went to a chiropractor, and that did help a little for awhile...(but you have to be careful - it can also do damage.) But it was finding an excellent, compassionate doctor, who believed me, that really gave me some quality of life back. I hope your sister has found one of those good docs. It sounds like she has. (Mine is also a PCP, by the way. A lot of Fibromites are treated by rheumatologists, but by no means all.)
Have you noticed our first thread, "Fibro 101"? There's a wealth of information there. There are threads on common co-existing conditions (that's a tongue-twister, eh?
) "what else could it be?", a looong list of symptoms, and different treatments...and more I can't remember right now.
One important thing to remember is that we're all different as far as what helps us - as Joy said. This applies to meds, exercise, diet, you name it.
I hope you'll keep posting - and maybe your sister will, too. The support here is great.
Debbie
