Can endometriosis cause shoulder pain during periods?
The short answer
Yes, endometriosis can cause shoulder pain during your period, most commonly when it affects the diaphragm, especially on the right side. Shoulder pain can have many causes, but a clear pattern linked to your menstrual cycle is an important clue.
Yes, endometriosis can cause shoulder pain that flares around your period, most commonly when it affects the diaphragm (especially on the right side). Pain from irritation and inflammation in this area can be felt in the shoulder or upper arm and may be sharp, achy, or worse with deep breathing or coughing.
Because shoulder pain can have many causes, the most important clue is a clear cyclical pattern that follows your menstrual cycle and/or occurs alongside other endometriosis symptoms. In a small subset of patients, symptoms above the diaphragm can overlap with thoracic endometriosis and include chest pain, shortness of breath, or (rarely) lung collapse around menses.
If you’re noticing predictable shoulder or chest symptoms during your period, our team can help you sort out whether they fit diaphragmatic/thoracic endometriosis or a look-alike condition and plan the right next steps, often starting with a detailed symptom timeline and targeted imaging when appropriate. If surgery is part of your plan, careful inspection of the diaphragm can be important even when symptoms are subtle. You’re welcome to reach out to schedule a consultation so we can review your history in detail.

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.
Is shoulder pain more common with right-sided diaphragmatic endometriosis?
Often, yes: people with diaphragmatic endometriosis frequently report right-sided shoulder pain. Left-sided or bilateral pain can also happen, so the side alone cannot confirm or rule out diaphragmatic involvement. The pattern, especially flares with your menstrual cycle, matters.
Can endometriosis cause rib or shoulder pain?
Yes, endometriosis can sometimes cause rib or shoulder pain, most commonly when it involves the diaphragm, the muscle under your lungs. Symptoms that predictably flare just before or during a period can point toward endometriosis in the diaphragm or chest.
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.
