Leg Pain and Sciatica with Endometriosis and Adenomyosis
Pain that radiates from the pelvis into the hips, thighs or down the leg can be a sign of endometriosis or adenomyosis, and it can feel like sciatica. A key clue is pain that follows your cycle.

When it flares
It often builds in the days before your period, peaks during bleeding and can flare around ovulation. Leg pain that's there all month still deserves a check.

When to get help
Leg pain that comes back with your period, or hasn't eased with sciatica treatment, is reason enough to see an endometriosis specialist.
Keep track
For two or three cycles, note the cycle day, where the pain starts, how far down the leg it goes, which side and how it feels. It's the most useful thing to bring to your first visit.
Speak with Us
Book a visit if it:
- Comes back with your period or ovulation
- Comes with painful periods, pelvic pain or painful sex
- Hasn't eased with usual sciatica treatment
- Makes it hard to walk, sleep or work
- Comes with tingling or burning around your period
Your first visit
We go through your history and your notes, then map out next steps together, whether that's tests, imaging or treatment.
When it needs a specialist: How to choose an endometriosis surgeon
What it feels like
How patients often describe it
- It's a deep ache in my hip and thigh.
- It shoots from my buttock down my leg.
- My legs feel heavy during my period.
- It burns and tingles when I sit.
It can ache, burn, pull or shoot, starting deep in the pelvis or buttock and spreading to the hip, groin or thigh, or down the back of the leg; some feel tingling in the thigh or knee. It can affect one leg or both, or switch sides. For some it peaks around bleeding; for others it's there most days, worse with long sitting.
Why it happens
Pain from the pelvis
Endometriosis can inflame the pelvic lining and nearby tissue, and scar tissue (adhesions) can pull on organs. The pelvis shares nerve pathways with the hips and legs, so pain that starts there can be felt down the leg, even when no nerve is directly involved.
Adenomyosis
Adenomyosis is tissue like the uterine lining growing into the uterus's muscle wall. Around your period, its intense cramping, inflammation and pelvic pressure can spread through shared nerves into the hips, thighs or legs, and feel like sciatica. It often comes with heavy periods, and with endometriosis.
Endometriosis on the nerves
Less often, endometriosis grows on or near the nerves deep in the pelvis that run to the leg, such as the sacral nerve roots or the sciatic nerve. It can cause shooting pain that follows your cycle and, over time, numbness or weakness.
Tight muscles, sensitized nerves
Pelvic floor and hip muscles, including the deep buttock muscle called the piriformis, can tighten to guard against pain and press on nearby nerves. A nervous system that has hurt for years can also turn the volume up.

“Sciatica that follows your cycle deserves a look at the pelvis, not just the spine. Tell us where the pain starts and how far it travels; that map tells us where to look.”
Why it's often missed
Leg pain is often blamed on the back, the hips or a slipped disc, so tests stay on the spine. A disc problem and endometriosis can also coexist. The clues are pain that follows your cycle, or that comes with painful periods, pelvic pain, painful sex, or bowel or bladder pain.
A normal spine scan doesn't rule out a cause in the pelvis, and even a pelvic MRI can miss endometriosis near a nerve.
How it's diagnosed
Track two or three cycles
Note where the pain starts, how far it travels, which side and when it flares.
Rule out other causes
Disc, hip, blood-vessel and nerve problems can cause similar pain, and more than one can be present.
A careful exam and imaging
A specialist maps changes in feeling and tender spots in the pelvis. Ultrasound or MRI can show adenomyosis, and MRI can show disease near a nerve, though a normal scan doesn't rule it out.
See an endometriosis specialist
A surgeon experienced with deep endometriosis and pelvic nerves can decide whether laparoscopy makes sense. Bring your notes.
Treatment options
Treatment depends on what's driving the pain, and often combines several approaches.
- Medical
Hormonal therapy
Can calm cycle-driven flares for some, though it doesn't remove endometriosis.
Hormonal Therapy - Medical
Pain relief
Anti-inflammatories, and nerve-pain medicines or nerve blocks when pain burns or shoots.
Pain Management - Surgical
Excision surgery
Removes endometriosis at the root when pain persists or deep disease near nerves is suspected.
Surgery overview - Surgical
Treating adenomyosis
Options range from hormonal therapy and uterus-sparing treatment to hysterectomy in select cases.
Adenomyosis care - Support
Pelvic floor therapy
Relaxes guarding muscles, with nerve glides and hip work that can ease leg pain.
Pelvic Floor Therapy - Support
Everyday relief
Heat, gentle stretching, pacing, TENS and sleep support can ease flares alongside treatment.

Questions people ask
Can adenomyosis cause leg pain, or is it only endometriosis?
Both adenomyosis and endometriosis can contribute to leg pain. With adenomyosis, intense uterine cramping and pelvic pressure can send pain into the hips, thighs, or legs, often alongside pelvic floor muscle tightening that amplifies symptoms.
Can endometriosis cause sciatica or leg pain?
Yes, endometriosis can cause sciatica-like symptoms and leg pain in some patients by growing in or near the sciatic nerve or causing inflammation and scarring that create nerve pressure. Pain may worsen before or during a period, but it doesn’t have to be cyclical.
Can adenomyosis cause hip pain?
Yes, adenomyosis can contribute to hip pain as uterine inflammation and cramping refer pain through shared pelvic nerves. Hip pain is not specific to adenomyosis, but worsening before or during your period with heavy bleeding or painful periods makes it a stronger suspect.
Endometriosis or herniated disc: how can I tell?
Endometriosis pain often flares with your cycle, while disc-related back or leg pain more often changes with spine movements. There’s no reliable at-home test, and both can coexist, so a symptom history, targeted exam, and appropriate imaging help distinguish them.
Can endometriosis cause leg numbness or tingling?
Yes, endometriosis can be associated with leg numbness or tingling in some patients when pelvic nerves are irritated or compressed. These symptoms can also come from other causes, such as spine or hip issues, vascular problems, or neuropathy.
Can endometriosis cause arthritis-like joint pain?
Yes, endometriosis can be associated with arthritis-like joint pain in some people. Whole-body inflammation may show up as aching or stiffness, but the association does not prove causation, and persistent joint pain deserves evaluation for other conditions.
