This eventually crusted over and healed up, but the blister
was very painful. I went to an emergency treatment center who took a swab sample from the blister
and sent away for
STD tests. The results were all negative for STDs. I had a burning sensation at the tip of my penis the night before the lesion appeared, but no fever
or other discomfort. I was prescribed a 7 day course of amoxicillin.
