Back in April, my boy friend and I had been diagnosed with Chlamydia and both of us received one dose of Azithromycin. Prior to April my boyfriend did not experience any symptoms nor after taking the medication. Recently, in September – approximately 5 months after taking the dose, he has been feeling symptoms, I wanted to know what is the likelihood that the antibiotics did not cure him? He claims he has not had any sexual interaction with anyone else, is it possible that he re-infected himself in the genital area? (I read that the Chlamidya bacteria, although clears up in genitals can live in the gut?)

Symptoms:
Swelling on pubic bone, penile discharge, pain in one testicle, pain in ankles
