Hello, I am a mid-30's male who noticed a reddish/purplish rash on the right glans and shaft of the penis in Nov. last year after being with my girlfriend for about 2 months. The doctor said it did not look like herpes. It was never a cluster of bumps, but did eventually ulcerate and then heal up after about 10 days. I thought it might be trauma, possibly from her IUD, but did get HIV and HSV I/II tested at that time ( about 2-3 weeks after ). All was negative. In any case, this recurred in the exact same spot with itchiness ( no pain ) and a rash in May though not as severe. After an additional recurrence in July, I was retested in August ( 9 mos. after 1st problem ) and had the focus HSV test for I & II...again both negative. I called the lab, but they would not provide exact numbers to me. I recently saw the doctor again...professor with extensive STD experience...with another recurrence (4th) - sudden itchiness and reddish rash in the same spot...exact same sharp borders of redness, but no bumps or pustules. After a week, it sort of dried up with flaky white skin, then went away. He said that without an ulceration or bumps there was nothing to send for PCR - and that this was just NOT herpes and could be an atopic reaction or dermatitis of some sort. I just wanted to see what you thought of this...I'm glad that I've tested HSV I & II negative twice now, but the symptoms just sound so c/w HSV and nothing else really? It's very hard to proceed with life, relationships etc. without a clear diagnosis. Thanks - should I have my immune system tested ( IgG or IgG subclasses to make sure it's normal...i.e. that I can make HSV antibodies?
