Can endometriosis cause chest pain?
The short answer
Yes, though uncommon, endometriosis can cause chest pain when it affects the diaphragm or, more rarely, the chest cavity. Pain is often cyclical, flaring right before or during a period, but chest pain has many possible causes and needs careful evaluation.
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 conditions, its pattern and timing matter, but they don’t replace a careful evaluation. If your symptoms recur 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.

Questions people ask next
All deep disease questionsIs my chest pain cyclical and possibly endometriosis-related?
Chest pain tends to be cyclical when it predictably flares in the same part of your menstrual cycle, and endometriosis could be contributing. Tracking timing, location and breathing-related symptoms for 2–3 cycles can make the pattern clearer.
Is my shoulder or chest pain from diaphragmatic endometriosis?
Diaphragmatic endometriosis can cause shoulder or chest pain that tends to be cyclical and frequently right-sided, flaring before or during your period. Many non-gynecologic causes can also explain this pain, especially if it’s left-sided or not tied to your cycle.
When are thoracic symptoms an emergency?
Sudden, severe chest pain, new or worsening shortness of breath, or faintness should be treated as an emergency, especially around your period. These symptoms can rarely reflect a lung complication linked to endometriosis and need immediate evaluation.
What are common symptoms of thoracic endometriosis?
Thoracic endometriosis symptoms include chest pain or tightness, shortness of breath, and pain in the shoulder or upper back, often flaring around your period. In some cases, a collapsed lung or fluid or blood around the lung can recur around menstruation.
