Now, I have suddenly popped an unknown blister on my
gums, right where my
gums meet my
tongue, under my wisdom tooth. The open blister is on the gums, I cannot see it, and it does not hurt, even when I drink or touch it.
Could be oral herpes? I see nothing around the area, nothing is swollen, and only the side of the opening (which is all I can see) is red. There are no other blisters.
