Tension or tenderness of the pelvic floor muscles can be associated with endometriosis and can contribute to painful sex. 

Physiotherapy provided by a pelvic health physiotherapist usually includes exercises and other instructions to teach how to relax the pelvic floor muscles. This can help reduce tension of these muscles. 

By relaxing the pelvic floor muscles, physiotherapy can help reduce pain during sex and improve sexual function. 

Pelvic health physiotherapy is a good addition to your pain management plan.

Chronic pain is complex, so you may also want to consider surgerymedication or mental health support in as well.
