Why Do I Experience Lower Back and Abdominal Pain After Sex?

Experiencing lower back pain and abdominal discomfort after sexual intercourse is often a sign of an underlying medical condition. It is advisable to undergo a gynecological examination and an ultrasound to determine the cause and appropriate treatment. Below are some common reasons for this type of pain:

Pelvic Inflammatory Disease (PID)
One possible cause is pelvic inflammatory disease. During a gynecological exam, if there is tenderness in the uterus or thickening and pain in the adnexal areas, it may indicate PID. This condition can lead to significant abdominal and back pain during or after sex due to movement of the uterus when the cervix is touched. Treatment typically involves antibiotics to fight infection, often combined with herbal medicine to promote blood circulation and reduce inflammation.

Endometriosis
Another potential cause is endometriosis. If there is no uterine tenderness or thickening in the adnexal regions, but painful nodules are found in the posterior fornix or along the uterosacral ligaments, this is a key sign of endometriosis. Women with this condition may feel deep pain during intercourse, especially if the affected areas are touched. This often results in post-sex abdominal and back pain. Treatment options include hormonal therapies such as oral contraceptives, mifepristone, or the use of an intrauterine device like the Mirena coil. In more severe cases, surgical removal of the affected tissue may be necessary.

If you regularly experience pain after intimacy, it's important to consult with a healthcare provider to rule out serious conditions and find effective relief.
