I have this rash lesions one on my upper butt crack, one on my inner thigh, 3 in back of my leg and one on my butt cheek. Ive never been diagnosed with herpes and never had an out breack on my genitals.. Still my Dr. Says is herpes. He gave me acyclovir but is not helping at all is been 2 wks and the lesions are still there. Can it be something else??
