Regarding the oral thrush: Are they sure it's the meds that caused it?
I honestly don't know anything about
oral thrush, but I did develop dry mouth last year, and also got several rapidly developing cavities. My dentist said it's likely my health causing the issues, but not sure if he meant health in general, or from the dry mouth from the meds.
Anyway, I went off my meds (have the doctor's okay on that, which is important), and have taken warm baths/showers, using the heating pad, topical creams, and taking acetaminophen when I need it. I do miss the meds (which worked faster and better), but just can't chance getting more dental issues.
I did a search on oral thrush and there's quite a lot of info on it. Maybe you'll want to do that, too, if you haven't already.
Hope someone here can offer more help, and perhaps have dealt with the same thing you have.
Best wishes and keep posting! BTW, did you read fibro 101, the first thread listed? Lots of good info.
