I just noticed that I have a cluster of quite bright red spots on the tip of my penis, there are also a couple on the underside of my foreskin. They are located in the top half of the head, more or less surrounding the penile opening. They are relatively painless (although I can feel a very slight pain). It can't be an STD as I have not had sex. Could it be a reaction to Doxycycline (an antibiotic)? I have only been on it for 6 days for acne. I am not going to take it today, so if it is because of this, will it clear up on its own or will I need to see the doctor? Thanks in advance.
Now some of the tops have turned to a whitish colour. I'm quite worried now..
