Does anyone have any idea what could cause widespread dryness? I've tested negative for autoimmune several times.
But did notice a few years ago when I would lay down to sleep, that I could notice my eyes, sinus, mouth, and lips feel kinda dry. It didn't bother me, but just noticable within 5 minutes of laying down. Then when I would wake up, my eyes were kind of dry, but was gone right after I got up. Also noticed for a year or so before the dryness started, that my sinus mucus production went away. i.e. I used to blow my nose all day long, but then the mucus went away to where I didn't have to blow my nose anymore, and no more mucus build up when sleeping.
One day I woke up with eyes on fire. Shirmers tests was 0. And ever since had problems with dry eyes bothering me. A couple of months later on the same day, my siuses and mouth dryed up and started bothering me. That was rough for a couple of months, then my sinus was better here and there, and my saliva came back, but it would get dry here and there. Then later also noticed my lips feeling dry alot.
The Doctors won't do anything. But was wondering if anyone had any ideas what could be causing all the dryness? Especially the dryness that started bothering me started suddenly. Makes me think neurological.
