Red Spots Jock itch?

Hello,
About a month ago I had strep throat and was placed on antibiotics.  Although they worked, I noticed that I did sweat a lot, and in the process afterwards, my groin became itchy.  Around the same time, I would masturbate and noticed a  mild burning sensation, like a friction burn.  Initially I thought it was from the lubrication I was using.  So I used Lamisil for about a week and the itch has subsided for the most part.  But I noticed two red spots on my penis, one on the head and a smaller one on the shaft.  No fluid, not raised.  After Lamisil I started using a Neosporin/Jock itch cream for about a week so far and the itch on my scrotum and penis seems to be going away, but the spots (which look like friction burns) remain.  By the way, they dont burn, itch at all.  Is this persistent jock itch?  Thanks!

No, it's probably just redness left over from irritation.  Jock itch (fungus) generally affects the inner thighs, not the penis.  I suggest you do nothing and watch the redness fade.  If it's still there in a month, show a doctor.

Best.
