Hi, doc! Sorry to bother you again, but I'm really worried. I know that it is said that oral sex with a woman is little to no risk, but I have my doubts. It was my only exposure in a long time. Tested negative at 9 weeks and 12 1/2 weeks. PCR RNA and PCR DNA undetectable at 6 weeks. PCR RNA undetectable at 9 weeks. Should my doctor used a PCR DNA at 9 weeks? These tests give me much hope, but my symptoms persist 13 and 1/2 weeks after possible exposure. White tongue that stings at times. Very sore, heavy feeling in neck. Prickley/slight itchy feeling on skin. Red bumps appearing on my upper legs (this one really scares me). I ran on Saturday and my lower legs felt extremely heavy. There is a white substance where my gums meet my lower middle teeth (unless it is the gumb that is white). Not having the flu symptoms 2 to 4 weeks after possible infection, would that delay the onset of antibodies. How you one tell when someone turns positive after infection on one who does not have symptoms? I need some help!!
