You may experience discharge, bleeding or pain from the anus.
Chlamydia is tested either by a urine sample, or a swab from the cervix, vagina, throat or anus.
Chlamydia is treated effectively with antibiotics. However, if complications are suspected, a longer course of treatment is given.
If you have symptoms, they will usually start to go away a few days after you have started treatment.
If you still have symptoms a week after starting treatment, see your doctor again.
If you have a vagina, untreated chlamydia can cause pelvic inflammatory disease (PID) which is an infection of the uterus and fallopian tubes. PID can lead to infertility.
If you have a penis, untreated chlamydia can lead to infertility.
