Why does chlamydia cause testicular pain?

Short answer
Chlamydia can cause testicular pain when infection spreads into the epididymis, causing inflammation and tenderness in the structures beside the testicle.
This answers one question. It is not a diagnosis and does not replace an assessment by a licensed doctor.

Why the pain can develop
The epididymis is a coiled tube at the back of each testicle that stores and carries sperm. Chlamydia may move from the urethra into this area and cause epididymitis. Swelling and inflammation can create an ache, tenderness, heaviness, or discomfort that is more noticeable with movement.
Testicular Pain is a common presentation of Chlamydia. However, pain in a testicle can also arise from injury, hernia, urinary conditions, or a twisting of the testicle. An examination and appropriate infection tests help distinguish between these possibilities.
What to do next
Book a same-day medical or sexual health assessment for new testicular pain, particularly with burning urination, discharge, or recent sexual exposure. A clinician may examine the scrotum and arrange urine or swab tests. Take prescribed treatment as directed and avoid sexual contact until you have received advice about treatment and partners.
Recent sexual partners may need testing and treatment even if they have no symptoms. This helps prevent ongoing transmission and reinfection after treatment.
When urgent care is needed
Get emergency care immediately for sudden severe testicular pain, a high-riding or unusually positioned testicle, marked swelling, nausea or vomiting. These features can occur with testicular torsion, which needs urgent assessment. Seek prompt care as well for fever, increasing redness, or worsening scrotal swelling.
Questions for your clinician
Ask whether the pain could be epididymitis, which tests will be done, whether other sexually transmitted infections should be checked, and how partners should be informed. Ask what changes in pain or swelling should lead you to return sooner.

It can cause discomfort on one side or both sides when inflammation involves the epididymis.
Is sudden testicular pain always chlamydia?
No. Sudden severe pain needs emergency assessment because torsion and other causes must be considered.
