Hi, so i have been tested for STDs and everythings negative. no swollen glands, no other symptoms..my family says they have seen this before and im totally fine but i just wanted to see what others thought too. its some sort of mouth irritation, i dont overuse mouthwash, but it seems like i have irritated my mouth somehow, its hard to explain and the site wont let me post pictures yet but there is a white streak and then it seems very red and veiny right underneath that, the white streak is not raised..it actually looks like more of a bruise if anything like i brushed too hard or drank too much soda...to be honest, i was worried i had contracted HIV or something, but im a known hypochondriac...no sore throat just weird lookin scary gums how do i make them better??
