Nine years ago I had unprotected sex with somebody who wasn't my partner; I never got myself checked but did have some pain at the time and occasionally I've had a twinge that's passed quickly.
Recently I've been having those pains again but more severely, along with stomach pains etc., and went to the doctor, thinking I was having kidney stones but after the above conversation he diagnosed Chlamydia and prescribed a oneday course of antibiotics; my urine sample has been sent off for testing.
My question is this: is it really likely that after all these years the symptoms will appear?
