Back pain is one of the most common complaints among women, yet many people don’t realize that this discomfort can sometimes be linked to gynecological conditions.
One of the most overlooked causes is endometriosis, a chronic condition that affects millions of women worldwide. While it’s most known for causing intense pelvic pain, heavy periods, and fertility challenges, endometriosis can also trigger persistent or cyclical back pain that disrupts daily life.
This comprehensive guide explains how and why endometriosis causes back pain, what the symptoms feel like, and when to seek medical support.
Understanding Endometriosis
What Is Endometriosis?
Endometriosis occurs when tissue that behaves like the lining of the uterus (the endometrium) grows outside the uterus. This tissue can develop on various pelvic and abdominal structures such as the ovaries, fallopian tubes, uterosacral ligaments, bladder, bowel, or pelvic walls.
Because this tissue responds to hormones just like the uterine lining, it thickens, breaks down, and bleeds during each menstrual cycle. But unlike regular menstrual blood, this displaced tissue has no way to exit the body, causing inflammation, pain, cysts, and scar tissue (adhesions).
How Endometriosis Causes Pain
The pain associated with endometriosis comes from three main mechanisms:
- Inflammation: The trapped tissue releases inflammatory chemicals that irritate nearby nerves.
- Adhesions: The body forms scar tissue in response to repeated inflammation.
- Nerve involvement: Endometrial tissue can grow near or around nerve pathways, sending pain signals to different areas of the body, including the back.
Can Endometriosis Cause Back Pain?
Yes. Back pain is a well-recognized but often misunderstood symptom of endometriosis. Women frequently overlook the connection because the back pain doesn’t always feel like typical muscle strain or injury. Instead, the discomfort often stems from inflammation and lesions deep in the pelvic cavity.
Why Back Pain Happens
Endometriosis-related back pain typically occurs due to:
- Lesions on the uterosacral ligaments, which connect the uterus to the spine
- Pelvic inflammation spreading to nearby nerves
- Adhesions that pull on pelvic structures
- Deep infiltrating endometriosis involving the lower spine or rectovaginal area
- Sciatic nerve endometriosis, a rare but severe cause of radiating back and leg pain
Where the Pain Is Usually Felt
Back pain related to endometriosis may be felt in the:
- Lower back
- Sacrum or tailbone area
- Hips or outer pelvis
- Buttocks or thighs (radiating pain)
What Endometriosis-Related Back Pain Feels Like
Common Characteristics
Back pain caused by endometriosis can feel:
- Dull, aching, or throbbing
- Sharp during period days
- Persistent and deep
- Aggressive during ovulation
- Worse after sexual intercourse
Some women describe it as a heavy or pulling sensation caused by adhesions restricting movement inside the pelvis.
How It Differs from Regular Back Pain
Back pain linked to endometriosis has a unique pattern:
- Cyclical timing—pain often worsens around menstruation
- Accompanied by pelvic symptoms, not just muscular discomfort
- Pain does not improve significantly with posture changes, stretching, or rest
- Often accompanied by fatigue and bloating
Other Symptoms That May Come With Back Pain
Endometriosis-related back pain rarely occurs alone. Additional symptoms may include heavy periods, severe cramps, pain during intercourse, painful bowel movements, bloating, fatigue, and difficulty conceiving.
When Back Pain Could Indicate Deep Infiltrating Endometriosis (DIE)
Deep infiltrating endometriosis is a more advanced and painful form of the condition. Back pain is especially common when:
- Lesions affect the uterosacral ligaments
- Tissue grows in the rectovaginal septum
- The bowel or bladder is involved
- The sciatic nerve is affected, causing numbness or tingling down the leg
Women with DIE may find everyday movements—sitting, bending, or walking—especially painful during flare-ups.
Diagnosis: How Doctors Determine the Cause of Back Pain
Medical History & Symptom Review
Your doctor will review your menstrual cycle, pain pattern, and other symptoms.
Pelvic Exam
A pelvic exam may reveal tenderness, nodules, or tension in ligament areas affected by endometriosis.
Ultrasound or MRI
These imaging tools help detect cysts, deep lesions, and adhesions.
Laparoscopy
Laparoscopy is the gold standard for diagnosing endometriosis. It allows doctors to see and often remove lesions during the same procedure.
Conditions That Mimic Endometriosis-Related Back Pain
Other conditions that may cause similar back pain include sciatica, fibroids, ovarian cysts, pelvic inflammatory disease, or common musculoskeletal strain. This makes accurate diagnosis essential.
Treatment Options
Medical Treatment
Doctors often recommend:
- NSAIDs for inflammation
- Hormonal birth control to regulate or suppress periods
- Progesterone therapy
- GnRH agonists or antagonists
These treatments help reduce symptoms but may not eliminate all lesions.
Lifestyle Support
Helpful lifestyle adjustments include heat therapy, gentle stretching, yoga, an anti-inflammatory diet, stress management, and hydration.
Surgical Options
For severe cases, especially with nerve involvement or adhesions, laparoscopic excision surgery may offer significant long-term relief. Removing lesions and scar tissue often reduces both pelvic and back pain.
When to See a Doctor
You should consult a healthcare provider if:
- Your back pain worsens around your period
- Pain interferes with your daily life
- You experience pain during intercourse or bowel movements
- Symptoms do not improve with home remedies
- You’re trying to get pregnant without success
Early diagnosis can prevent complications and improve your quality of life.

Endometriosis can indeed cause back pain, especially when lesions affect pelvic nerves, ligaments, or deeper structures. While this pain can feel overwhelming, the right treatment plan can make a powerful difference.
