Symptoms of chlamydia can affect both men and women with the infection; however, chlamydia is often known as a "silent" disease because most people who are infected show no symptoms. Some common symptoms of chlamydia in women include abnormal vaginal discharge, a burning sensation when urinating, lower abdominal pain (or stomach pain), and pain during intercourse. Men with symptoms of chlamydia might have discharge from their penis, a burning sensation when urinating, and burning and itching around the opening of the penis.

 

There are also some serious complications related to the symptoms of chlamydia. For example, up to 40 percent of women with untreated chlamydia develop pelvic inflammatory disease (PID), which can cause permanent damage to the fallopian tubes, uterus, and surrounding tissues. While complications from symptoms of chlamydia are rare in men, genital chlamydial infection can cause arthritis that can be accompanied by skin lesions and inflammation of the eye and urethra (Reiter's syndrome).
