Can you tell if you had pelvic inflammatory disease from having chlamydia? If so, how long do u have to have PID to cause damage?

Uncertain. Chlamydia is the most common cause of PID, but most chlamydial infections don't result in PID. There are no data on duration of PID and permantent tubal damage, but the longer infection is present without treatment, probably the greater the risk of permanent damage. Also, second and later chlamydial infections often cause more damage than first infections.
