The problem concerns about red dots on penis head.
several years ago, I had one red dot appeared on penis head no itchy, no pain. It had faded away and I had not paid much attention.
Two weeks ago, I had terrible tooth pain with pus, i went to doctor he cured me and and prescribed antibiotic (which i I've got for 5 days) . The same week I had high fever and feeling weakness. At the same time my penis head went almost totally red and with 2-3 red dots. One dot was on that same place that I have mentioned above. Actually they didn't itch, but when touching i felt pain. Now, total redness went away but two this red dots remained.
Can you tell me the possible causes?
