Dear OldKarl, my eyes are so dry they are being treated by doctors and have also lost all teeth due to this. Gerd, two arthritis, Hashimotos, Rheumatoid and Psoriatic arthritis, Diabetes and right now the kidneys are ready for dialysis. These are among eight other medical problems to long to list. As well as now having Shingles. VERY IMPORTANT: Perhaps this Corona virus is prompting and producing the Shingles?
