Can endometriosis cause upper back pain? Although endometriosis is most commonly associated with pelvic pain and painful menstrual periods, some patients also experience discomfort in the upper back, shoulders, or rib cage. In certain cases, these symptoms may be associated with endometriosis affecting the diaphragm or structures within the chest. This is sometimes called diaphragmatic or thoracic endometriosis.
Endometriosis-related inflammation, referred pain, and overlapping musculoskeletal conditions may also contribute to discomfort outside the pelvis. However, upper back pain is common and has many possible causes, so it should not automatically be attributed to endometriosis.
At the Endometriosis Center of Excellence, Dr. Rachael Haverland focuses on specialized endometriosis evaluation and treatment, including laparoscopic excision surgery. Understanding the possible relationship between endometriosis and upper back discomfort can help patients recognize relevant symptoms and seek appropriate medical evaluation.
Can Endometriosis Cause Upper Back Pain?
Yes, endometriosis can sometimes be associated with upper back pain, particularly when the condition affects the diaphragm or other structures outside the pelvis. The diaphragm is a large muscle separating the chest cavity from the abdomen. It plays an important role in breathing and shares nerve pathways with areas around the shoulders.
When endometriosis develops on or near the diaphragm, irritation may contribute to pain that is felt in the shoulder, upper back, or rib cage. However, this form of endometriosis is less common than pelvic disease. Many patients with upper back discomfort have unrelated causes, including muscle strain, spinal conditions, or other medical problems.
How Can Endometriosis Cause Pain Beyond the Pelvis?
Endometriosis is a chronic inflammatory condition in which tissue similar to the uterine lining grows outside the uterus. It most commonly affects structures within the pelvis, including the ovaries, pelvic lining, and surrounding tissues. Pain associated with endometriosis can sometimes extend beyond the area where lesions are located. Possible contributing mechanisms include inflammation, referred pain, muscle tension, and increased sensitivity within the nervous system.
Referred pain occurs when discomfort originating in one part of the body is perceived in another area because of overlapping nerve pathways. However, not every episode of upper back pain in someone with endometriosis is caused by referred pain. A medical evaluation is needed to determine whether the symptoms are related to endometriosis or another condition.
Can Pelvic Endometriosis Cause Pain Between the Shoulder Blades?
Pelvic endometriosis is more commonly associated with lower back and pelvic discomfort than pain between the shoulder blades. Chronic pelvic pain may contribute to changes in posture, muscle tension, and movement patterns. These factors can sometimes affect the back and surrounding muscles.
However, there is limited evidence that pelvic adhesions routinely pull on tissues in a way that directly causes pain between the shoulder blades. Persistent upper back pain should therefore be evaluated for musculoskeletal, neurological, and other potential causes.
Why Might Upper Back Pain Worsen During Menstruation?
Some patients notice that shoulder, rib, or upper back discomfort becomes more pronounced before or during menstruation. A recurring menstrual pattern may be an important clue when evaluating possible diaphragmatic or thoracic endometriosis. Endometriosis-associated symptoms can fluctuate with hormonal changes throughout the menstrual cycle.
However, cyclical pain alone does not confirm endometriosis. Other conditions may also produce symptoms that vary over time. Keeping a record of symptom timing can help healthcare professionals identify patterns and determine whether further investigation is appropriate.
What Is Diaphragmatic Endometriosis?
Diaphragmatic endometriosis occurs when tissue resembling the uterine lining develops on or near the diaphragm. It is a form of extrapelvic endometriosis, meaning the disease is located outside the pelvis. Some patients with diaphragmatic endometriosis experience shoulder, upper abdominal, rib, or upper back discomfort. Others may have few noticeable symptoms. The severity and location of symptoms vary depending on the individual and the extent of involvement.
How Does Diaphragmatic Endometriosis Cause Shoulder Pain?
The diaphragm receives sensory signals through the phrenic nerve. This nerve also contributes to sensation in the shoulder region. When the diaphragm becomes irritated, pain signals may be perceived in the shoulder rather than directly over the diaphragm. This is called referred pain.
Patients may experience discomfort near the shoulder tip, upper back, or lower rib cage. Symptoms may become more noticeable around menstruation, although not every patient experiences a predictable cyclical pattern. Shoulder pain can also result from joint, muscle, cervical spine, or other conditions, so its presence alone does not establish diaphragmatic endometriosis.
Is Diaphragmatic Endometriosis the Same as Thoracic Endometriosis?
The terms are related but not identical. Diaphragmatic endometriosis refers to disease involving the diaphragm. Thoracic endometriosis is a broader term describing endometriosis associated with structures in or around the chest cavity, such as the pleura or lungs. The pleura is the thin membrane surrounding the lungs and lining the chest cavity.
Thoracic endometriosis may be associated with chest pain, shoulder discomfort, coughing, or respiratory symptoms. In rare cases, it can be associated with catamenial pneumothorax, a collapsed lung occurring in temporal association with menstruation. Because chest symptoms can indicate serious conditions, they require appropriate medical evaluation.
Can Thoracic Endometriosis Cause Shortness of Breath?
Yes, thoracic endometriosis can sometimes be associated with breathing difficulties. However, shortness of breath is not specific to endometriosis and may result from conditions affecting the lungs, heart, or circulation. A pneumothorax, pulmonary embolism, or other serious medical condition can cause similar symptoms.
New or unexplained shortness of breath, particularly when accompanied by chest pain, requires immediate medical evaluation. Patients should not assume that breathing symptoms are caused by endometriosis simply because they occur around menstruation.
What Are the Symptoms of Upper Back Pain Associated With Endometriosis?
Symptoms vary depending on whether endometriosis affects the pelvis, diaphragm, or thoracic structures. Some patients report upper back discomfort alongside familiar pelvic symptoms. Others may experience symptoms involving the shoulders or ribs that initially appear unrelated to a gynecological condition. Possible symptoms include: Read more in Hip, Back, and Leg Pain: How Endometriosis Affects Pelvic Nerves.
-
Upper back or shoulder discomfort
-
Pain near the shoulder blade
-
Rib or upper abdominal pain
-
Pain that becomes more noticeable around menstruation
-
Discomfort with deep breathing
-
Chronic pelvic pain
-
Severe menstrual cramps
-
Pain during intercourse
-
Bowel or bladder symptoms associated with menstruation
These symptoms are not exclusive to endometriosis. Their presence should prompt an appropriate evaluation rather than an assumption about the underlying cause.
Can Endometriosis Cause Pain Under the Ribs?
Yes, diaphragmatic endometriosis may sometimes be associated with pain near the lower ribs or upper abdomen. The discomfort may be intermittent or occur in relation to the menstrual cycle. However, pain under the ribs can also result from gastrointestinal conditions, gallbladder disease, muscle strain, or other medical problems.
The location of pain alone cannot identify its cause. A healthcare professional may consider the timing, associated symptoms, and examination findings when deciding which tests are appropriate.
Can Endometriosis Cause Pain in the Right Shoulder?
Diaphragmatic endometriosis is often described in association with right-sided symptoms, although pain patterns can vary. Some patients report discomfort near the right shoulder tip or upper abdominal region. However, right shoulder pain is common and can have several causes, including musculoskeletal disorders and referred pain from other organs. A cyclical pattern may raise suspicion for diaphragmatic involvement, but it does not confirm the diagnosis.
Does Upper Back Pain Always Mean Endometriosis Has Spread?
No. Upper back pain does not necessarily indicate that endometriosis has developed outside the pelvis. Muscle tension, spinal conditions, nerve irritation, and unrelated health problems are common explanations for upper back discomfort. Even when a patient has confirmed pelvic endometriosis, a new symptom should be evaluated independently. The severity of pain also does not reliably indicate the extent or stage of endometriosis. Read more in Pelvic Pain After Eating: Endometriosis Signs.
How Is Upper Back Pain From Endometriosis Diagnosed?
Diagnosing possible diaphragmatic or thoracic endometriosis requires careful consideration of symptoms, medical history, and other potential causes. A healthcare professional may ask whether pain occurs around menstruation, whether it affects breathing, and whether the patient has previously been diagnosed with endometriosis. Evaluation may involve imaging studies or referral to appropriate specialists. However, no single symptom or test can identify every case. You may also find What is Endo Belly? Causes and Relief Strategies helpful.
Why Is Tracking Your Menstrual Symptoms Helpful?
A symptom diary can help patients identify patterns that might otherwise be difficult to recognize. For example, recording upper back pain alongside menstrual symptoms may reveal whether discomfort repeatedly occurs during a particular phase of the cycle. Useful details to track include: For more detail, see our article Why Is My Endometriosis Pain Getting Worse.
-
The date and duration of pain
-
The location of discomfort
-
Pain intensity
-
Whether symptoms coincide with menstruation
-
Associated pelvic symptoms
-
Whether breathing or movement affects the pain
-
Treatments attempted and their effects
This information may help guide clinical evaluation. However, symptom tracking cannot confirm or exclude endometriosis on its own.
Can MRI Detect Diaphragmatic Endometriosis?
MRI may help identify certain forms of deep or extrapelvic endometriosis. In selected cases, imaging can support evaluation of suspected diaphragmatic involvement. However, small or superficial lesions may not be visible. A normal MRI does not necessarily exclude diaphragmatic endometriosis. The usefulness of imaging depends on the suspected disease location, examination protocol, and experience of the interpreting clinician.
Can Ultrasound Diagnose Thoracic Endometriosis?
Pelvic ultrasound is useful for evaluating certain forms of pelvic endometriosis, including ovarian endometriomas and some deep lesions. However, routine transvaginal ultrasound is not designed to evaluate most structures within the chest. When thoracic endometriosis is suspected, clinicians may consider chest imaging or other investigations depending on the symptoms. These tests may also help identify alternative explanations for chest or upper back discomfort.
Is Laparoscopy Necessary to Diagnose Diaphragmatic Endometriosis?
Laparoscopy can allow direct examination of portions of the diaphragm and upper abdominal cavity. When appropriate, tissue may be removed for pathological examination. However, surgery is not required for every patient with suspected endometriosis. Clinical findings and imaging may guide initial treatment decisions.
In selected cases involving suspected thoracic disease, evaluation may require collaboration with specialists experienced in chest conditions. The decision to pursue surgery depends on symptoms, clinical findings, potential benefits, and procedural risks.
Frequently Asked Questions
Can endometriosis cause upper back pain?
Yes. Endometriosis may sometimes contribute to upper back discomfort, particularly when the diaphragm or thoracic structures are involved. However, upper back pain has many possible causes and is not a specific sign of endometriosis.
Why does my upper back hurt during my period?
Upper back pain during menstruation may be associated with muscle tension, referred pain, or another condition. In some patients, a recurring menstrual pattern may raise suspicion for diaphragmatic or thoracic endometriosis.
Can endometriosis cause shoulder blade pain?
Yes, diaphragmatic endometriosis may occasionally cause referred discomfort near the shoulder or shoulder blade. However, musculoskeletal and spinal conditions are more common causes of pain in this area.
Can endometriosis affect the diaphragm?
Yes. Diaphragmatic endometriosis is an uncommon form of extrapelvic endometriosis that may cause shoulder, rib, upper abdominal, or upper back discomfort.
Can endometriosis cause chest pain and shortness of breath?
Thoracic endometriosis may be associated with chest pain or breathing symptoms. However, these symptoms can also indicate serious medical conditions. New chest pain or unexplained shortness of breath requires immediate medical evaluation.
Does upper back pain mean my endometriosis is severe?
Not necessarily. Pain intensity and location do not consistently correspond to endometriosis stage or anatomical extent. Upper back discomfort may also be unrelated to endometriosis.
What Treatments Help Upper Back Pain Associated With Endometriosis?
Treatment depends on the underlying cause of the discomfort. When upper back pain is associated with endometriosis, healthcare professionals may consider hormonal treatment, appropriate pain management, or surgery in selected cases. However, treatment should not begin with the assumption that every episode of upper back pain is caused by endometriosis. A comprehensive evaluation may identify musculoskeletal, neurological, or other conditions requiring different approaches.
Can Hormonal Treatment Help?
Hormonal therapies may help reduce endometriosis-associated pain for some patients. These treatments work by influencing hormonal activity that contributes to endometriosis symptoms. Options may include certain hormonal contraceptives or other medications prescribed for endometriosis management.
The appropriate choice depends on individual health factors, treatment goals, and potential side effects. Hormonal treatment may reduce symptoms but does not necessarily eliminate all endometriosis lesions.
Can Pain Medication Relieve Upper Back Discomfort?
Nonsteroidal anti-inflammatory drugs, commonly called NSAIDs, may help manage some types of pain. However, their effectiveness varies depending on the cause of discomfort. Patients with persistent symptoms may require a broader pain management plan. Medication decisions should consider existing health conditions, possible interactions, and individual treatment needs. Patients should consult their healthcare provider before starting or changing medication.
When Is Excision Surgery Considered?
Laparoscopic excision surgery may be considered when endometriosis is contributing to significant symptoms and surgical treatment is appropriate. The procedure involves identifying and removing endometriosis lesions while attempting to preserve healthy surrounding structures. When diaphragmatic or thoracic endometriosis is suspected, surgical planning may require additional expertise and coordination.
Some cases may involve collaboration with specialists experienced in thoracic surgery. Surgery may improve symptoms for selected patients, but it does not guarantee complete or permanent pain relief. The potential benefits and risks should be discussed carefully before proceeding.
Can Physical Therapy Help With Upper Back Pain?
Physical therapy may be useful when muscle tension, posture, or movement-related problems contribute to discomfort. Patients with chronic pelvic pain sometimes develop secondary muscle guarding or changes in movement patterns. A qualified physical therapist can assess these factors and recommend appropriate rehabilitation strategies. Physical therapy does not remove endometriosis lesions, but it may help manage overlapping musculoskeletal symptoms.
When Should You See an Endometriosis Specialist?
Persistent upper back discomfort that occurs alongside severe menstrual symptoms or chronic pelvic pain may warrant further evaluation. A specialist may be particularly helpful when symptoms follow a recurring menstrual pattern or when previous assessments have not identified a clear explanation.
Patients with suspected diaphragmatic or thoracic endometriosis may require a coordinated approach involving gynecological and other medical specialists. At the Endometriosis Center of Excellence, Dr. Rachael Haverland focuses on specialized endometriosis care, including laparoscopic excision surgery and individualized treatment planning.
A comprehensive evaluation can help determine whether endometriosis may be contributing to symptoms and whether medical treatment, additional imaging, or surgical assessment is appropriate. Seek emergency medical care for sudden chest pain, unexplained shortness of breath, fainting, or severe breathing difficulty. These symptoms should never be attributed to endometriosis without urgent assessment.
Conclusion
Upper back pain and endometriosis can sometimes be connected, particularly when the condition affects the diaphragm or thoracic structures. Diaphragmatic endometriosis may contribute to referred pain involving the shoulders, ribs, or upper back, and some patients notice symptoms that fluctuate with menstruation. However, upper back pain is not a reliable indicator of endometriosis on its own.
Musculoskeletal conditions, spinal disorders, and other medical problems can cause similar discomfort. Recognizing symptom patterns and seeking an appropriate evaluation can help patients understand the possible causes of pain and explore individualized treatment options. For patients experiencing persistent upper back discomfort alongside endometriosis symptoms, specialist assessment may help clarify whether the conditions are related.
