9 days ago I had unprotected sex with a woman who claimed she was clean. I had vigorous sex with my girlfriend 4 days later. On the 5th day, I started having pain urinating and painful swollen lymph nodes. I immediately went to the clinic and got tested and treated for chlamydia and gonorrhea. Also the doc noticed 2 very small pimples in the hairline about an inch apart. They were not red or touching each other and I had had similar acne like that before and been tested for herpes so I was pretty sure it was just one of the bacterial infects. The doc gave me the gonoreah antibiotic injection, Zythromiacin and Cypro. I called to get the chlamydia/gonoreah results and they told me I was negative. It has now been 4 days since the initial symptoms, I am still following the antibiotics course and I am terrified because I don't know what it could be. I am gonna get tested for HPV, herpes and HIV tomorrow but I cannot go on not knowing. Is there anything I should get checked for that I haven't thought of?
Other than STIs, what causes painful urination, swollen/painful lymphnodes?
