Re: sore/itchy throat...white bumps on tounge
About a 2 years ago I had the same symptoms.... really sore throat and white bumps on my tongue with lots in the back. This is gonna sound really gross, but the bumps started coming off like the top layer of skin on my tongue was shedding. I could rub a paper towel over my tongue and they would come off. The skin underneath was red and sore, kind of like the skin under a blister from a burn.
Anyway, I was really freaked out and went to the doctor. He said it was just a viral infection in my throat. About the time the bumps started coming off, my throat started to feel better. I was over it completely in about 3 weeks. It was impossible to drink any hot beverage while the bumps were coming off because the skin on my tongue underneath was soooo sensitive.
About 1 week after mine started, my daughter got the same thing and the same thing (skin comming off tongue) happened to her. I've had it once or twice since then.
I didn't have any other rashes as you describe tho.
