I a 53 yr old woman in pretty good health and shape. Don't smoke, do drink a couple glasses of red wine in the evenings. My grandson is being treated with antibiotic for strep throat, on Friday Aug 2nd I was feelling dizzy, achy and it hurt a little to swallow. I thought I was sick with strep throat. By Sunday I felt very bad and laid around, my tongue now has several ulcers and I am unable to taste anything. Their is nothing wrong with my throat today Aug 7th (no redness or swelling or puss pockets) but my tongue still has ulcers. 1) What's wrong with me and 2) What can I do for these ulcers and 3) Are they a danger sign
