I had a girlfriend several years ago with HR HPV and genital herpes type 2. I have type 1 oral. Recently had a Western Blot ordered and a Herpeselect right after I dated her that said I was negative for type 2 and positive for type 1 (as expected). I recently had a terrible outbreak of raised red irritated itchy bumps all over my groin, inner thighs, some on my penis, abdomen and even a few on my ribs. Of course I panicked. I did recently wear and work out in heavily bleached boxers that I definitely bleached more than usual, likely too much. I am hoping I simply had a bad allergic reaction, although I have sensitive skin I have never had a reaction that significant.  I do not think I have ever comtracted any bacterial STDs and have not had any sexual comtact of any kind for several years.  

First I discovered one red raised ‘hive’ on the the head of my penis and some general irritation on 17th.  18th in the morning had the doctor swab using Amplivue NAAT test (is this test good?  Is it inferior to PCR?) and the result was negative. The next day the lesions/hives were wide spread in the boxers short area, particularly in places where the seems of my boxers rubbed, including more on my penis.   I was back into my Doctor on 20th for another swab of a different new larger lesion/hive on the head of my penis, which was also negative.  Doc thinks herpes unlikely given the swabs.  Doc also did a culture of the most itched/infected area on my abdomen which was positive for Enterococcus faecalis, but I am thinking this wasnt the causative agent.  I suspect any ulceration is from abrasion and no lesions appear to be opening up or leaking fluid. They did itch a lot, and though mostly healed, some still remain.  Had a dermatologist give me a second opinion and he did not suspect STD, but rather bed bugs or scabies.  Ive done zero traveling and work from home and have no other problems.  That diagnosis is no good.  Was the Amplivue a good swab test?  Do we know how accurate the WB is? Is a sudden allergic reaction to bleach a reasonable diagnosis? Ive always been sensitive to it, even occasionally would get a few hives where the waist band rubbed too much, but this was much worse.  So what STD if any should I be thinking of?
