Is my chest pain cyclical and possibly endometriosis-related?
The short answer
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.
Chest pain tends to be cyclical when it predictably flares at the same point in your menstrual cycle, most often in the days leading up to bleeding, during your period, and sometimes around ovulation. People often notice a recurring pattern in where it hurts (such as the same side each month, sometimes under the ribs) and what sets it off, like deep breaths, coughing, or twisting.
Tracking your symptoms for 2–3 cycles can make this pattern much clearer. Note the timing relative to your cycle, where the pain is, how it feels, and whether it comes with breathing-related symptoms, shoulder/rib pain, or upper abdominal discomfort. If you’re seeing a consistent cycle-linked pattern, our team can help evaluate whether endometriosis could be contributing and discuss which next steps make sense for you.

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 endometriosis cause chest pain?
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.
