Hello, About 2 months ago I had std like symptoms. Discharge and some burning when I urinated. I took a full std check and everything was negative so my doctor decided to get rid of the symptoms I should go on doxycycline for a week so I did and for the most part it cleared all symptoms. The only thing that remains since I finished the doxycycline is the tip of my uretha looks red/ irritated and a glued shut look. My doctor than prescribed me cefixime, I just finished the cefixime and it still looks the same what could this be.
