My GF was on UTI antibiotics at the time, and was tested
for STDs 2 months ago (all clear). No
pain, just a red spot with slight swelling and small cracks in the skin. It seems minor since there's no itch/burn/pain. But it has been there for 2 weeks. A few days after this appeared there was minor discharge from the crack in the skin. I had it swabbed and my doctor tested it for herpes, which came back negative.
