7 weeks ago, a period of time when I was having unprotected oral sex with a questionable partner, I began having a sore throat
, which lasted about 2 weeks. 5 weeks ago the roof
of my mouth became painful and swollen. After two days the blister burst and some fluid came out. After that, the blister was no longer painful and shrank to about half the size. It is now smooth and elongated, sort of vein shaped, and is at most an inch long.
