Hi There. I am recently into a new relationship w/ a women who just got out of a 3 yr relationship and assured me she is clean and gets regular check-ups. About 11 days ago I performed oral to vagina and we had intercrouse. To note, I have been heavy weekend drinking and getting no sleep for the past 3 weeks and it's been wearing me down. I also have had swimmer's ear trouble in the past........ earlier this week i had a fever for 2 nights, along w/ night sweats. those are now gone. now, i have a mostly dry cough, one lymph node on the side of face which i have ear pain (small, but if i feel close enough it's tender), some canker sores in my mouth which kinda hurt, and, which seemed to come overnight, a somewhat bigger red, shallow (not raised at all, quite the opposite), irregular-shaped mouth ulcer on my gums which hurts when i eat. when i brush my tongue across it, it doesn't hurt, but it's pretty smooth. it's also right above this tooth that's been giving me some problem over the years with cavity / filling, etc. and i don't think it's filled correctly...... Is this any type of canker sore or STD, or seem dental related, or maybe like a tooth or ear infection??? PLEASE let me know your thoughts!!!!!! I've been freaking out over the past few days about it and it's all I think about, stressing over it bad. THANK YOU.
