Is my chest pain cyclical and possibly endometriosis-related?
The short answer
Chest pain is cyclical when it predictably flares at the same point in your menstrual cycle, and endometriosis could be contributing. Tracking timing, location, triggers, and breathing-related symptoms for 2–3 cycles can help clarify the pattern.
Chest pain tends to be cyclical when it predictably flares at the same point in your menstrual cycle, most often before or during your period, and sometimes around ovulation. Although uncommon, endometriosis can cause chest pain when implants affect the diaphragm or, more rarely, the chest cavity (thoracic endometriosis). Pain may recur on the same side or under the ribs, feel sharp with deep breaths, coughing, or twisting, and travel into the shoulder or upper back.
Chest pain or tightness before or during a period, including pain in the middle of the chest, has many possible causes, such as chest-wall conditions like costochondritis, so timing alone cannot establish the cause. Tracking symptoms for 2–3 cycles can clarify the pattern: note when they occur relative to your cycle, their location and character, triggers, and any breathing-related symptoms, shoulder or rib pain, or upper abdominal discomfort.
If symptoms consistently recur around your cycle, especially alongside pelvic pain, painful periods, or known endometriosis, you can contact our team for a consultation about whether diaphragmatic or thoracic endometriosis may be contributing. We can discuss an individualized evaluation and next steps, including imaging review and surgical options when appropriate.

Questions people ask next
All deep disease questionsIs 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.
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.
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.
Can imaging detect diaphragm or chest endometriosis?
Sometimes imaging can suggest endometriosis on the diaphragm or in the chest, but normal imaging doesn’t rule it out. Even MRI can miss small or superficial lesions, though imaging can help map other potential causes of chest symptoms and support surgical planning when suspicion is high.
