One week ago I performed cunnilingus on a coworker who was visiting from out of town. About a year ago we had kissed and on this night we both got very drunk and kissed and I pleasured her for about 5-10 minutes.
The next night I noticed that my chin was very tight and sore (makes sense I suppose) and I had a very small cut on the inside of my upper lip. Over the next few days that cut disappeared but my upper lip still felt a bit painful and swollen in the middle where the veins are. Yesterday the middle of my upper lip swelled a bit but today it is back to normal.
This morning I awoke to find a "pimple" under my tongue on the right side of my saliva gland at the base of my tongue. It is on the bottom / side of my tongue not the bony part of my lower mouth. The area is red and swollen and more lightly colored in the middle. It just seems like a single eruption and not a cluster.
Since one or two days after our encounter I have had swollen lymph nodes in my neck, been feeling fatigued, a bit dizzy, had a sore throat, dry mouth and felt nauseous. It is mainly due to these symptoms and the emergence of the sore under my tongue that I am concerned. It all just seems very coincidental.
I have felt itching on my lips for a few days now but have not had any sores on the outside of my mouth. I think the itching might just be caused by my worrying mind :/
Is there any possibility that this may be herpes or another STD? If not is it possible I may have caught some other type of infection in my mouth / throat from cunnilingus?
I am going to see my doctor on Friday. Does this sound at all like it could be an STD?
