Thanks for your advice. I went to see a doctor a few hours after you responded.
He agreed that it was most likely not herpes or HPV. He said it was a fungus and prescribed 2 creams (Nystatin and Flucinonide) and a pill (Fluconazole). They seems to be helping so far. After only a couple of days the steroid cream has reduced the inflammation a bit and the intense burning itch is relatively under control. I do have a couple of additional questions though that I will also ask my new doctor. After reading a bit on-line, I realize I should also mention that I am circumcised.
First, the past couple of mornings I have been awoken early by INTENSE itching. I reapply the creams and that helps except that this morning when it stopped it almost instantaneously on all but one part of my penis just below the head on the underside which continued to itch pretty bad for a little while. I assume that that is a normal condition for a fungal infection after only 2 days of treatment?
Second, the doctor advised me to apply the two creams together twice daily (morning and night), but I have had to apply them 3 times the last couple of days to control the itching. Is there a significant danger of over dosage of either the anti-fungal or the corticosteroid?
Third and most importantly, as I said before, the steroid cream has reduced the inflammation of the bumps/lesions/blisters (not sure what the appropriate term would be for these) sufficiently so that a small dark center is visible on most of them. As I said before, my girlfriend recently started to shave her pubic area. I distinctly remember being "stabbed" several times on and about the head of my penis during contact by the stubble. I seem to remember the bumps appearing soon after followed soon (several days) by the intense itching/burning sensation that is familiar to me from my experiences with athlete's foot. It started with approximately 4 bumps, 2 on the top of the head and 2 much larger below them on the shaft below the head that converged into one relatively large and elongated one. Subsequent bumps appeared later on the "high traffic" and more sensitive areas following almost immediately (hours or a day) further "usage."
Caution... laymen's theory ahead....
I wanted to run what I think happened by you and get an educated opinion. I had normal or possibly excessive growth of fungus on my skin that was asymptomatic. The "stabbing" incident(s) and continued, probably excessive, usage caused the fungus to enter the skin through what appear to be small, shallow punctures in the affected areas. The smaller bumps that do not appear to have the puncture are mostly located in the "high traffic" areas were the fungus entered small friction abrasions that were noticeable and present. In short, the "trauma" caused an otherwise harmless or mild fungal growth to manifest into a subcutaneous (I know that mean under the skin, but I'm not sure weather it is specific to just below the top layers or complete penetration) infection which produced the relative severity of the symptoms.
Finally the question. What do you think of my armature diagnosis?
Thank you again for your time and I apologize for my ignorance and the long-winded questions.
