Monday morning I noticed a rash(non-itchy!) on my chest. Hours later it had spread to my torso/back/arms and legs. I thought it was some allergic reaction. The only thing I had taken medicine wise within the previous few days was my generic allegra for my seasonal allergies, and a tablet or two of Drixoral--which had never caused me any issues in the past.
I went to my primary doctor who is a internal medicine specialist. He wanted to look at the bottom of my feet. He thought I had syphilis. I told him that I had gotten tested for all STDs(HIV, syphilis, etc.) three weeks earlier and all came back negative. He had me give blood for a syphilis test. He was confident that the test would come back positive. It didn't. He mentioned something about "prozone phenomenon" and suggested I get a biopsy of one of the rashes. The labs for the biopsy will be in this coming Monday. He had me get a penicillin shot today(Thursday).
I've read that it is usual that a person with syphilis will have rashes on their palms and/or on the soles of their feet. I have neither. I am anxiously awaiting the lab results. What if they show that I don't have syphilis? What kind of specialist should I ask to see?
