So for the past 6-7 months I've been suffering from a recurrent infection in my pubic region. It usually starts with a red, very swollen patch 3-5mm across, asymmetrical in shape. It's not painful, though it can itch on occasion. The hair follicles swell and eventually harden and the skin around the hair peels back leaving an abscess which heals in about a week or so. The swelling reduces dramatically but for the affected follicles, which remain raised and swollen. They are not painful, and produce no visible discharge, blood or pus. Occasionally I'll see what look like tiny whiteheads, but vanish after a few hours leaving flaking skin.
I've applied Bactroban ointment which seems to hasten healing, tea tree oil, which does apparently nothing, and antifungal cream which just burned a lot. Neosporin actually may have made the infection worse, as the first time I had a lesion I applied Neosporin to the area, only to have it spread within a few days.
To make a long story short, I've undergone repeat testing for Herpes though my genitals have (thankfully) never been affected in any way. I've always tested negative for HSV1, though early tests for HSV2 were indeterminate. My most recent test was negative for HSV2 using an IgG blood test (results were in normal range).
But I still keep getting these breakouts! They're quite unseemly and I've had at least five in the past 6 months, usually around the same area. I want to know what the cause would be, since it doesn't appear to be staph or bacterial (no pus or pimple-like boils) and not herpic (no pain, obvious blisters, ooze or crusting, outbreaks are more frequent than generally associated with HSV and negative testing). Is it contagious? Should I be concerned? Can it be prevented?
