Hello.  I am a 34 year old male, uncircumcised.  For approximately the last month, I have had the outlines of a vague "ring" come and go on the head of my penis.  It is usually about the size of a dime, but the size and shape vary.  This "ring" is not always a complete circle, but it looks like circular imprints or indentations in the skin.  It is not painful to the touch, but I do on occassion feel a slight radiating ache or discomfort from the area when I have it.  Sometimes the skin inside this "ring" will take on a wrinkled appearance.  Is this possibly some type of fungus or ringworm on my penis?

Prior to this, in mid July, I had a rash type outbreak of little red bumps all over the head of my penis (no pain, no blisters, no discharge, perhaps only slightly itchy).  I went to my doctor, who said it was just an allergic reaction of some sort and should clear up on its own.  It did, but a few bumps kept recurring, lasting approximately 4 or 5 days, with approximatley the same amount of time in between recurrences.  I went back to my doctor in September, who inspected them again and said it was probably a yeast infection I picked up from my wife.  He advised I rub Lamisil on it twice a day for two weeks.

After using the Lamisil, I no longer have the bumps but now I have this strange "ring".  I went back to my doctor to have him take a look, however the symptoms were very vague at the time and almost invisible, so he could not offer any meaningful guidance at the time.  It is difficult to schedule a visit with my doctor when the symptoms are very visible, as the intensity changes very rapidly in a short period of time.  It can appear very clear and prominent, and in a few hours be practically unnoticeable, and then a few hours later be very prominent again.

I have since tried using both Lamisil and Clotrimazole regimens.  As I said, the symptoms pass after about a week, but I get the feeling it is more a result of "running its course" rather than due to the medications.

Do you have any ideas on what this is and what an appropriate treatment would be?  Also, any chance that this might be STD related somehow?

Thank you very much.
