I have been tested for after only receiving oral. I took an instant syphilis test with 99.5% accuracy. And was negative.
About 8 months later I developed a very itchy scrotum without a rash. It has contributed to itch on and off for about 8 months.
I also have a burning sensation when I urinate.
I have tested negative for all stds but I’m worried that the instant test may have been a false negative.
Do these symptoms sound like syphilis?
