Welcome to HCM.
The symptoms may be a infection of your throat due to the oral sex
. It may be treated easily with some antibiotics like Erythromycin
. If you are worrying about HIV, you can go for HIV DNA PCR test. It will become reactive within three to four weeks after the last infectious encounter. If it came negative you need not worry about HIV. Gonococcal Pharyngitis
may be another cause for your problem if your contact had that infection.
You please meet a Dermatovenereologist and get examined by him and assertain you are free from HIV/STD
Get well soon. Dr S.Murugan
