I gave oral sex to my boyfriend 5 days ago (Monday night), I woke up the next day (Tuesday morning) with a sore throat. My throat has gotten progressively worse and my tonsils are now swollen and exhibiting white pus spots, and my throat is extremely painful and red. My glands on my neck are also very swollen and I have had a fever for the last day and a half. Is it possible that these symptoms are a result of the oral sex, or just a coincidence? Is it an STD or some other bacterial infection? Will penicillin cure what I have even if it's an STD and not strep throat?
Thanks for your help.
