 [ Symptoms ] hi i am not sure if i have genital herpes or not basically around may i developed sores around the buttocks i had blood tests may 7th culture testmay 14th and even a biopsy june 12th but all were negative for herpes i was prescribed mupirocin and the sores went away after 2 weeks last week sept 21 i had sores that looked and felt similar to the ones before but less severe this time i used the mupirocin and they went away after a few days i am worried do i have herpes even after all of those tests were negative [ Disease ] you can always retest again for the herpes virus or have another skin biopsy by a dermatologist but if those tests are negative and you respond well to an antibacterial medication herpes is a virus you probably do not have herpes but rather some type of recurrent skin infection
