I have had chlamydia since i was a virgin and i been prescribed azithromycin twice in the past 4 yrs and they both failed to cure me. what should i do?

Many issues: I find it odd that a virgin carries chlamydia, but it could be acquired with heavy petting. That aside, treatment failure can occur when the sex partner is not treated at the same time, with a new infected exposure gives it to you, or if the diagnosis was wrong in the first place. The most common reason for repeat disease is sex with an infected partner some of which have no symptoms.
