I was diagnosed with chlamydia about three months ago, which was three weeks after exposure. I took 1g of azithromyin and a 7-day script of doxacycline. I subsequently tested negative twice but my symptoms of burning while unirnating, discomfort at the tip of the penis have not gone away. Could this be prostatitis or could there be another infection that I haven't tested for that's causing urethritis? Follow up gonhorrea, herpes and HIV are all negative. During this time, I've also experience lower abdomen pain, urgency to uninate and unsteady stream. Those symtoms have improved but the burning while urinating and penis discomfort are still present. I've never had any penile discharge. I also bike ride about twice a week but it never bothered me before the chlamydia infection. My uro inidcates it could be anxiety related but the symptoms are definitely real. Any advice would be great..... thanks.
