I have been getting very small red bumps under the foreskin of my penis for several months. The bumps do not hurt, and and very small. I am worried they might be herpes. However, there are several other things they may be related to. I had a very bad reaction to antibiotics I was on just before the bumps started coming in. I read somewhere that antibiotic use can sometimes cause a yeast infection in men. Also, I have had a recurring rash on my arm from a cast I had taken off around the time I started getting the bumps.
Yes I am sexually active, but in a monogamous relationship.
Lastly, I have been getting the bumps at a frequency that seems highly unusual for herpes. I have an occurrence almost on a weekly basis lasting 2-3 days and they seem to be getting very slowly worse as time progresses.
My question is statistically speaking what are the chances of this being herpes given that I am having occurances at such quick intervals? (annualized it would be appox 50 a year)
