I have had this for a few days. At first, the red spots were all I noticed. They are fairly big (about 3/16" in diameter on average). I had no pain. My tongue had looked a little whitish before then, perhaps a day or two before. The day after I noticed the spots, I began tohave a slight sore throat that has gotten worse over the past 36 hours or so. Today, looking again, I was able to see a few spots further back on my tongue that looked swollen, andmy throat is very uncomfortable.
As I mentioned, the rest of my tongue may be slightly lighter than normal. It is hard to tell because of the red spots and the increasing pain.
I had flu A that kept me down for about 2 weeks. I went back to work on the 17th of Feb. but I haven't been totally "up to snuff."
I have MS and am on Rebif.
I also have inhalers - Qvar and Ventolin for mild asthma. ( I think one of the Qvar I have been taking is old.)
I have not had any tests for this. I have not been to a doctor yet, although I am considering going to an urgent care tomorrow if this pain persists.
