I am new to the forum but have had fibromyalgia many, many years. Just read your post about having a flare with your voice getting hoarse. I went to the Grand Canyon & on the way back to the hotel the bus driver had fresh air blowing in. I have seasonal allergies & I ended up with what I thought was a bad cold. However, it never went away & what was left was a terrible dry cough. After seeing a doctor & with lots of test I was diagnosed with asthma & given inhalers that I use when needed. To this day I still have a chronic dry cough that isn’t as bad, provided that I stay inside my home. If I go out, especially spring or fall it is worse & people hearing me cough think I’m contagious, giving me bad looks. I have tried over the counter medication like Biotene, etc. & my dentist told me to Xylitol that didn’t work. So I sip my water or other fluids constantly & suck on sugar free hard candy. Not only do I have dry mouth, but dry eyes, nose, & ears.
Unfortunately, for me I have lost my singing voice. I used to sing high soprano & now I sound like a bullfrog. I rarely try to sing because my throat gets dry, etc. It has been about 25 years since I lost my singing vouce.
