Hey Chelle,
I was diagnosed with fibro a few months ago. A doc told me you can't get swelling like that with AS, felt a few points and said, "think it must be fm as well as AS.
I have just been OS for 2.5 weeks and forgot to take my Plaquenil. I could really feel my muscles after about a week. three days back on Plaquenil and a huge difference.
I have a whole cocktail of drugs too, slowly one by one they're dropping (my liver can't handle it). I can't get any of the TNF's due to government restrictions in oz.
Just know that you are not alone and can always come here for support.
Take care and keep smiling,
Rose
