I had brief unprotected oral and vaginal sex with an unknown partner. Besides being completely emotionally torn up, I felt a mild uncomfortable burn when not urinating. It doesn't hurt when I urinate, just when I'm not. I started feeling this the very next day, probably less than 10 hours afterwards. What could this be? I'm a day and a half into a Cipro prescription. I'm really freaked out by this. I know anxiety can play into this a lot, but I'm literally making myself sick over this. Can you help?
