Recently I got testing done which was a culture /smear test, hiv and syphilis. The results from the hiv test came back as negative and I have to wait three weeks for the syphilis results. The culture /smear came back that I had a bacterial infection and tested positive for clinical acgc and tears (not too sure if they're the same thing. For treatment I was given an injection in my bum and doxycycline 100 mg and flagyl 400 mg to be taken twice a day for a week. However, this past day I realize that my labia is swollen and has a hot feeling. What may be the cause of this?
