Can endometriosis cause chest pain?

Yes—while it’s uncommon, endometriosis can cause chest pain when implants affect the diaphragm or, more rarely, the chest cavity (thoracic endometriosis). This pain is often cyclical, flaring right before or during a period, and may feel sharp with deep breathing, coughing, or certain movements. Some people also notice pain that seems to travel into the shoulder or upper back.

Because chest pain can come from many different conditions, the pattern and timing matter, but they don’t replace a careful evaluation. If your symptoms are recurring around your cycle—especially alongside pelvic pain, painful periods, or known endometriosis—our team can help assess whether diaphragmatic or thoracic involvement may be contributing and discuss next steps, including imaging review and surgical options when appropriate.
