Hi, I have been getting a small rash above my pelvic bone that gets small blisters and turns red an itches.  It only happens about 3 times a year.  I am married and have been with the same partner for 7 years but this started to occur about 4 years ago.
Hello. Thanks for writing to us at Chat Doctor Seems most likely that this is herpes genitalia; recurrence and morphology of the rash seems to suggest this. Genital herpes is caused by a virus, herpes simplex virus (HSV Type 2); it is a sexually acquired infection from an infected partner. Herpes is a local infection i.e. the infection is localized to the area where it was first acquired. There can be relapses; relapses are caused by virus multiplication which subsequently travels down the nerve and causes fluid filled lesions. The episodes may be accompanied by Itching and burning sensation. I would suggest that you visit a dermatologist in your region for a confirmatory diagnosis. If I was the treating doctor I would like you as well as your partner to be tested for HSV by blood test. Treatment is with Oral antivirals like Acyclovir Or Val acyclovir. Regards
