About 6 or 7 months ago, I had unprotected sex with two separate partners. Both vaginal and anal. Not too long after, I developed a cold, sore throat, runny nose and what looked like pimples on my inner thighs. I broke some open and hard, round nodules came out. They looked almost like large blackheads. The cold went away after about 7 days and the bumps took just a bit longer. Of course I looked up tons of symptoms and now I feel it’s a cause for concern. Even more so when I found statistics for Washington ST, stating that there have been more than 15,000 HIV/AIDS cases recorded in Washington and about 3,000 people on average that have HIV and don’t know it. Some other symptoms like diarrhea have been present but no fever. I do not have a history of rashes and to my knowledge I am not allergic to anything. I'm nervous about getting tested, should this be a cause for concern?
