okay, one last question, even if i did have a STI such as the clap or chlamydia, wouldn't the treatment of antibiotics for my UTI take care of it either way?
Very likely so.
Also, could e-coli be the cause of both a sore throat and a UTI?
Possibly but not likely to cause the sore throat.
I'm mainly asking these questions for peace of mind, and i know my paranoia isn't warranted, however, i can't seem to stop this neurosis until i have at least a few answers to calm my nerves.
A lot of people react to recent sexual activity in a similar way that you are. Some of them tell us later that they were diagnosed with an anxiety disorder. Have you thought about talking to your doctor about your fears, Taken?
