50+ year old female. Married high school sweetheart. Never had any other sexual partner. Had cold sores since teenage years. Recent high level stress situation (family death). Had 3 cold sores back to back on lips. Shortly after, noticed pain, itching and blisters right inner buttock area, near rectum. I thought shingles brought on by stress. Doctor said herpes!!! Did a swab for PCR (?). No results yet. Doctor said I had "cold sores" on my butt! Started antiviral. Due to family stress situation, have not had sex in some time. Can the virus that causes cold sores just show up on the butt? Trying to educate myself thru online sites. Any help or thoughts would be greatly appreciated! Thanks!
