My doctor did a culture of my throat and penis to determine if I have chlamydia or gonorrhea. But he decided to go ahead and treat me for the above STDs. I was given a shot of an antibiotic yesterday and put on a regiment of doxycycline. How long will it before I start to feel better. I have had relief with the feeling of swollen testicles but my throat doesnt seem to be any better at all. I'm concerned for some reason that this isnt going to respond to treatment. It's probably just my anxiety but throat is really bothering me and it actually looks a little worse. Any thoughts?
