Had unprotected oral and vaginal sex twice with the same woman and soon after [approx 2 weeks] started to develope many strange symptoms. Became very tired to the point of having a hard time to hold my head up for a week straight, Developed a bumpy rash of white wiggly lines like a burn on the inside of my lower lip but went away after 2 days, Has since come back once, Had flu like symptoms for 2 days with nausea and diarrhea, Developed a patch of folliculitus on my chest and it stayed for over a month even with antibiotic treatment, My stomach started growling intensely with severe intestinal rumbling and discomfort accompanied by alot of gas and verry strange bowel movements, Developed a few small boils on my back and legs, My toenails have also all turned yellow. I went for detailed STD screening at 3 and 6 months post exposure and all tests were negative, Also had abdominal x-rays and stool sample done and all seemed normal, Any opinions on what this may be? Any suggestions on what I should test for?? Is this an STD or stress???
