[Question #5255] Red, hard pimple bump in groin

22 months ago
Hi.  Me, Male, 57, recently divorced after 30 year relationship.  Female 1. Unprotected vag on Mar 1, Mar 8 and Mar 13.  She has had very few partners in her past, I believe her to he a low risk person.  Female 2.  I consider a high risk person. Protected vag and oral on Mar 20. On Mar 26, a single red, hard pimple develops in pubic area at base of shaft in the hairline.  I thought I saw a head and tried to squeeze but nothing came out.  I applied hot compress in morning and night and also benzoyl peroxide in morning and night and neosporin during the day.  Bump completely gone after 4 days.  The bump was definitely below and above the skin, convex not concave. No blistering or ulcers.  I dont get many groin pimples and the timing really got me anxious.  On March 12 (16 days after the protected sex) full STD blood work.  IgG hsv 1 positive, IgG hsv2 negative, HIV negative, rapid RNA test.  All others were negative.   Are there any takeaways from this scenario, hopefully put my mind at ease concerning hsv2. Are more tests needed?

I think your appointment is today.  The bump at the base of your penis could be anything, including HSV 2, though from your description, it's very hard to tell.  Because you already have HSV 1, if you acquired HSV 2, the symptoms might be very minimal.  It's too bad that the bump was not swab tested when it first appeared.  Your antibody test was done too soon after the bump showed up to be accurate but the negative HSV 2 at that time is useful for a baseline value.  My suggestion would be to  retest 12 weeks from the encounter (you can do it also at 6 weeks and if negative, there is a 70% chance it will stay negative).  And if the bump ever comes up again, please go in for a swab test of the bump right away, when it first shows up.

Hi again.  Thanks for reply.  I just met with the GP.  He seems to believe, at least initially it is not Hsv2.  One, because everything is atypical ( location, non cluster, pimple like appearance in the skin not on it, no blistering and ulcers and speediness of time to heal) two...when I explained about the benzoyl peroxide I had applied he asked if it burned when applied.  I said no, why? He stated it typically burns when applied to herpes lesions.  I asked about the fact of a pimple presenting itself when its not normal for me...he said could easily be caused by a bacterial agent.  What is your experience with regards to skin to skin bacterial.  Does it occur with any kind if frequency? It seems to me different bacterial flora could potentially be an explanation.  Of course, I'm looking for reasons to explain this to myself with a positive outcome.  At any rate, it is agreed by all that additional testing will be done in the near future.

Also, I meant to include....does his benzoyl peroxide comment make sense as well?

It is certainly possible that people can transfer bacteria from one person to another through a sexual contact, no doubt about it.  I can't tell you the frequency of this happening however, that is not tracked by anyone that I know of.  Not sure about the benzoyl peroxide - seems like that would hurt no matter what on open skin but I don't know specifically regarding HSV.  I agree that future testing will be helpful for you in clarifying your situation.
