Why does pelvic inflammatory disease cause pain during sex?

Pelvic inflammatory disease is an infection-related inflammation affecting the upper reproductive organs. Inflammation can make tissues swollen and sensitive. During deeper penetration, movement may press against the cervix or inflamed pelvic organs, producing deep aching, sharp discomfort, or pain that continues afterwards. Protective tightening of the pelvic floor can add a layer of muscular pain.

Pain during sex may occur alongside lower abdominal pain, unusual discharge, bleeding between periods or after sex, fever, or burning when passing urine. These symptoms can have different causes, so an examination and appropriate tests are needed rather than relying on pain alone.

Pause penetrative sex if it causes pain and arrange a medical assessment, particularly if symptoms are new or accompanied by discharge, bleeding, or fever. If pelvic inflammatory disease is diagnosed, take prescribed treatment exactly as directed and ask when sexual contact can safely resume. Partners may also need assessment or treatment. Do not douche, because it can irritate tissues and make symptoms harder to interpret. Comfort measures should not replace evaluation of a possible infection.

Seek urgent care for severe or rapidly worsening pelvic pain, fainting, repeated vomiting, high fever, heavy bleeding, or possible pregnancy with pain. Prompt assessment matters because untreated pelvic inflammation can extend beyond the initial infection and may affect future reproductive health. Contact a clinician soon for persistent pain during sex, even without fever.

Could an infection explain my pain, and which tests are appropriate? Do I need treatment for a partner? When should symptoms improve, and what should I do if pain remains after treatment?
