I am a healthy and active 58 y/o male with lots of allergies for which I take shots, sudafed, zyrtec or allegra, flonase and advair. Last May I started experiencing dry mouth, squishy tongue, sometimes sweet tongue, The tongue issues seem only to be on the right side. Also a tingling of the tongue. My wife says I sound like I m smacking gum and gulping. Family history of diabetes. I ve consulted my GP who suggested an ENT which I ve seen twice to no avail. Dentist has no answers either. What s my next move? What specialist should I consult.
