Had all ars symptoms after 3 days of protected sex with csw. Thereafter tested duo at 3rd, 7th for hiv and it came back negative. And now it's 12th week from the incident and I had swollen node at neck side. Also I am having white tongue from 3 month. Yesterday I just found out a painless sore in mouth after googling it I am really frightened. Please help me. if I got any sexual infection, will that leads to cancer. As of now I am not on any medication other than just multivitamins.
