I've noticed a couple of blisters on my soft palette recently. One that was a blood blister about 3/4 the size of a dime on the right side of my soft palette, which has turned whiteish and is becoming smaller and is almost gone about 5 days after appearing, and then I just got another one on the left side that is not blood or pus filed, just white on top, a bit smaller, right beside my last molar.
Both of these blisters came on immediately after eating corn-based foods. I typically consume a very whole food diet and don't eat much junk, but the first blister began right after eating smartfood, and last night I ate some tortilla chips and the second blister started. I'm hoping that these blisters are due to the food and not an STI like throat/pharyngeal gonorrhea! I'm also under a lot of stress right now, and wonder if that might be contributing.
The sores do cause my throat to be a bit sore locally. There is no pus on my gums, and the blisters are pus free as well.
Hoping someone can help me out with this!
