Hi, if you used a condom nothing could get inside your penis so the sex worker had nothing to do with what ever symptoms your having.
Hey, I am on the same boat right now. I assume you don't have either gono or chlamydia, which means it can be another bacteria or virus causing your symptoms.
Many NSU are idiopathic, which means we can't find a bacteria causing it. The Mycoplasma Genitalium is a "common" cause and I am myself waiting for the test results. I am actually on doxy and after 5 days, the discharges mostly stopped, but I still feel pain and that the discharges will come back soon when I'll stop doxy. I am not a doctor, but I read that for Mycoplasma and maybe other NSU, it seems like Moxifloxacin is a more efficient treatment. Maybe you should ask your Dr after it ?
Good luck, hope we'll both get out of this very soon.
