33 year old white male here. Two and a half weeks ago I had unprotected vaginal sex with a 37 year old white female. We have sex a few times per year together. She had one sex partner in the past year in the beginning of September. He wore a condom and she was his first sexual partner since his std test 6 months before that. He was negative during that test. 4 days after sex with her, I started to feel sensitivity in my abdomen on my right side when my shirt would touch it. Over the next few days it started to include sensitivity on the right abdomen and right back. 4 days later, I noticed a small rash of 4-5 pimples on my abdomen to the right of my belly button. They never oozed and are in the process of healing up currently. I had a telemedicine visit with my doctor and they diagnosed me with shingles, mostly with the symptoms being the rash (that doesn’t look like a shingles rash from pictures on the internet) and the skin sensitivity on one side of my body. Another rash of two pimples showed up yesterday on my back in the area of my back that has been sensitive. I have no joint pain, but my back and abdominal muscles were sore for a week or so. I attributed that to playing golf a few times that week and having a cold and coughing a lot the week before.
I had no discharge or pain while urinating. I did take doxycycline (7 days) starting 7 days after the sex because of a sinus infection. The girl I had sex with got tested for gonorrhea and chlamydia one week ago by urine test and was negative, but she did take a course of amoxicillin clav for a week prior because of a dog bite. She had zero symptoms as well. Could this be disseminated gonorrhea or am I just freaking out for no reason. Should I just listen to my doctor and believe it’s shingles?
