Chlamydia is known as a "silent" infection because many people infected with chlamydia do not experience any symptoms. However, when symptoms do occur, they can vary between individuals and may include abnormal vaginal or penile discharge, pain or burning sensation during urination, pelvic pain, testicular pain, and rectal pain or discharge. In some people, chlamydia can present with lower abdominal pain, fever, and spotting between periods in women. It is imperative to understand that the lack of symptoms does not mean the absence of infection, which is why ongoing testing is so important, specifically for those who are sexually active or those with a bunch of different partners. If you suspect you may have been exposed to chlamydia or have any of the mentioned symptoms, it is recommended to seek medical attention for testing and appropriate treatment.
