on the shaft of the penis. I take minocycline (antibiotic) for acne, but had not taken it for about one month. I started taking it a couple days after the sore and swelling appeared, and both subsided within 3 days.
It has been almost five weeks since my encounter. I have not had any fever or noticed any enlargement of my lymph nodes. I did have a sore throat for a couple days recently, but that passed. Is a genital ulcer and swelling alone a common symptom of HIV?
You had condom-protected sex so you had no risk for HIV, which does not produce genital ulcers.
However, since you describe an ulcer it's possible that you may have caught syphilis. You should see a doctor for evaluation and testing to be safe, since it can result in serious complications if not treated properly.
