I had some unprotected sex with a random woman about 4 weeks ago. At first a couple of days after potential exposure, I noticed some small bumps on my penis that disappeared in about a day. I also noticed a blood blister on my scrotum, and my testicles had a very slight tingling burning sensation that has been coming and going. A couple days later I started getting a sore throat that seemed to mostly go away in about a week or two. I also started getting acne like bumps on my thighs, and have since started noticing these same bumps appearing on my body, like on my torso, near my genitals, wrists, sides of my fingers, and a few on my legs. They are very sporadic and only a few at a time, but they keep appearing and disappearing within a few days. I was tested for a few STI's a couple of days after the encounter, and retested again at 3 weeks for many of the same STI's but also others such as HIV and Herpes blood tests (which came up negative). There might also be some bumps on the very back of my tongue, but I can't tell if they are normal or not. I am very very nervous, and would really appreciate some insight into what you guys think. Even though I was tested, I wonder if it was not long enough to wait to administer a test. The provider I got the test from acted like it was long enough but I read some different things online now. Please help!
