Hi Frazzle
You poor old thing!!! You've really been through the wringer, haven't you? Well you're in good company, I'm afraid - most of us here have similar stories to tell with difficulties making contact with our Drs and Neurologists, or Neuries as we call them. but unlike many, I can subscribe to the saliva gland problem too. When I sounded out my dentist to have a tooth replacement, he x-rayed the jaw and told me that the bone had been softened by the radiation therapy beam which had [hopefully ] burned out the remains of a brain cancer problem, but in making its exit had fried my left hand side saliva gland. Now I knew why my mouth always seems so dry. Remember how Quinine always had an anti mosquito& anti Nat effect, Hydroxychloroquine has a similar effect on Lupus and Fibromyalgia. But contrary to D.Trump's ideas it doesn't cure COVID19 or any variants thereof! I've never suffered any side-effects from Hydroxychloroquine, other than benefits, but then, I have so many effects from the medicines I'm given after two brain tumours, Epilepsy, old age (78) etc , that even if Hydrox..... has side effects on me they are probably just mopped up and thrown into the waste bucket for disposal; well, my dear, I wish you all the luck you need, and by the way, my last appointment with my Neurie was carried out by Zoom, which saved a two hour journey through thick traffic. A win/win situation!
all the very best to you, just hang in there, and when it comes to pain - I virtually LIVE on a paracetamol every 4 hours
