I have had a bitter taste in my mouth and constant watery saliva for ~ 3 months. My tongue is cracking and my mucosa feels slimy and thin.
Angular celitis( spelling error) present as well. All of this is accompanied by dry eyes and a persistent hacking cough.

The cough has been present for over a year.

Any suggestions which do not include over the counter mouth washes and oral moisturizers. I have tried them all.

Also feeling weak
And motor functions are unsteady.

Uninsured 51 year old female.

Thanks for amy help.
