I have been tested back in May 2009 for HSV2 and HSV1 and my test results were negative, just as a regular check up for STDs. I am very rarely sexually active but last month I did perform oral sex on a male. We have discussed if either had anything, which we both said no. Though, 17 days later, I happened to look at my tongue and noticed there were three red circles/sores on the tip of my tongue...but one was more to the side of the tongue but still on the edge. They turned red and circular but went away in 4 days.
Just yesterday, I noticed a red circular formation starting to appear again on the tip of my tongue and today, it has a very tiny white puss looking bump on the edge of the center of the red circle. I'm starting to freak out it might be herpes, though I do not show any other lesions anywhere and the location seems unlikely compared to other spots herpes could form in the mouth. I am also diagnosed with Ulcerative colitis for about two years now, which I have read online that this can cause ulcers to appear inside of the mouth, but have not noticed this before. I have an appointment to see a doctor on Tuesday but just wanted some advice to help ease my mind a bit on figuring out what it could be.
