Why does chlamydia cause painful urination?

The urethra is the tube that carries urine out of the body. Chlamydia can infect this lining and trigger irritation, swelling and discharge. That inflammation makes the area more sensitive during urination. Painful Urination is a very common presentation of Chlamydia, but burning while passing urine also has other possible causes, including a urinary infection or irritation unrelated to a sexually transmitted infection.

Some people notice discharge, pelvic discomfort, bleeding between periods, or pain during sex. Others have few noticeable symptoms. A test is needed to identify the cause and to check for other infections that can occur at the same time.

Arrange a sexual health or medical assessment promptly. Testing may use a urine sample or a swab, depending on your body and symptoms. Avoid sexual contact until you have been assessed and follow the treatment plan exactly if chlamydia is confirmed.

Tell recent sexual partners that they may need testing and treatment. Partners can pass the infection back and forth even when they feel well. Do not use leftover antibiotics or share medication; the correct treatment depends on the assessment.

Seek urgent medical care for severe lower abdominal or pelvic pain, fever, vomiting, inability to pass urine, or worsening pain with swelling in the genital area. These symptoms need prompt assessment because they can occur with conditions that require timely treatment.

Ask which tests are appropriate, when you can expect results, whether partners need treatment, and when it is safe to resume sex. Also ask whether repeat testing is advised after treatment and what symptoms should prompt an earlier review.
