Hip Pain: When It’s Actually Coming From Your Spine

Hip pain is one of those complaints that sends you in circles. It hurts where you’d expect hip pain — in the side of the hip, the groin, or around the buttock — but movement or rest doesn’t change it the way you’d expect. Sometimes it responds to stretching. Sometimes it radiates down the leg in a way that feels more like a nerve problem than a joint problem.

That confusion often happens because the hip and the lower spine share nerve roots, muscle attachments, and movement patterns that are deeply interconnected. A problem in the lumbar spine can produce pain that feels exactly like hip pain. A problem in the sacroiliac joint — the joint connecting the spine to the pelvis — can do the same. So can the piriformis muscle, sitting just behind the hip joint, which can compress the sciatic nerve and mimic hip and leg pain simultaneously.

For many people dealing with persistent hip pain, the most useful thing to understand is that the source of the pain may not be where the pain lives.

The hip-spine connection

Your lumbar spine (the lower five vertebrae) is connected to the pelvis and hip region through muscle groups, nerve roots, and fascial chains. The nerves that travel down into the leg originate in the lumbar spine and sacrum — meaning anything that irritates those nerves higher up can produce symptoms that feel like they’re in the hip or leg.

The nerve roots most commonly involved:

• L3 and L4 — often refer pain into the front of the thigh and into the groin
• L4, L5, and S1 — commonly refer into the outer hip, buttock, and down the leg

This is why a herniated disc or degenerative changes in the lumbar spine often produce hip pain rather than (or in addition to) low back pain. The nerve irritation happens at the spine, but the brain registers the signal where the nerve travels — often in the hip.

The sacroiliac joint — a common and often missed source

The sacroiliac (SI) joint connects the base of your spine to your pelvis. When it becomes inflamed or moves poorly, it produces pain that almost always feels like it’s in the hip, buttock, or low back — but the hip joint itself is normal.

SI joint dysfunction is one of the more commonly missed causes of “hip pain” because it doesn’t show up clearly on hip imaging. X-rays of the hip joint look normal. The pain is real; the hip just isn’t the source.

Patterns that often suggest SI joint involvement:

• Pain centered over the buttock or just to the side of the tailbone
• Difficulty rolling over in bed or shifting weight from one leg to the other
• Pain when standing up from a seated position, especially after sitting for extended periods
• Discomfort that eases once you’ve been walking for a few minutes

Piriformis syndrome: when a muscle mimics hip and sciatic pain

The piriformis is a deep muscle that runs from the sacrum to the upper femur, passing directly over or through the sciatic nerve in most people. When the piriformis becomes tight or irritated, it can compress the sciatic nerve and produce pain and tension in the buttock that radiates down the leg — symptoms that look a lot like classic sciatica from a disc.

Piriformis-related pain is often worsened by sitting, especially on hard surfaces, and may ease with walking. It’s a common source of what patients describe as “hip pain” that imaging doesn’t explain.

Signs your hip pain may be spine or SI joint in origin

These patterns tend to point away from the hip joint itself:

• Pain that radiates down the leg or into the groin
• Pain that worsens after prolonged sitting, especially driving
• Pain that changes with low back movement, not just hip movement
• Hip pain that started after or alongside a low back injury
• Little or no pain with full hip rotation when lying flat

True hip joint problems — like osteoarthritis or labral tears — tend to produce pain that’s most significant with weight-bearing and internal rotation of the hip, and usually don’t radiate below the knee.

What our team evaluates

When hip pain comes through the door at The Roots Health Centers, we’re not just looking at the hip. We look at how the lumbar spine is moving, whether the SI joints are functioning symmetrically, and what’s happening with the piriformis and surrounding musculature.

Our neurological evaluation gives us an objective picture of how the nervous system is functioning in the regions served by the lumbar and sacral nerve roots. That helps distinguish mechanical spine involvement from other causes. We also assess movement patterns that point toward specific structures as the likely source.

The goal is to get the right answer about where the problem actually is — because care that targets the wrong structure doesn’t produce good results, no matter how well it’s delivered.

Frequently Asked Questions

Can a chiropractor help with hip pain?

Yes, particularly when the source is in the spine, sacroiliac joint, or surrounding musculature — which accounts for a large portion of hip pain cases. Chiropractic assessment helps identify where the problem is coming from, and care addresses that source.

How do I know if my hip pain is from my hip or my back?

Pain that changes with low back movements, radiates into the leg or groin, or worsens with prolonged sitting tends to point toward the spine or SI joint. Pain that’s focused at the outer hip and worse with walking and weight-bearing may be more hip-joint in origin. A proper evaluation makes this distinction reliably.

What is the SI joint and why does it cause hip pain?

The sacroiliac joint connects the base of the spine to the pelvis. When it becomes inflamed or restricted, it produces pain in the buttock and hip area that can be mistaken for hip joint pain. It’s a common and often missed cause of what patients describe as hip pain.

Does hip pain from the spine go away on its own?

Sometimes, particularly when it’s acute and secondary to a temporary nerve irritation. Chronic or recurring hip pain from spine or SI joint origins benefits from identifying and addressing the underlying cause rather than waiting it out.

If your hip pain hasn’t responded to rest or standard approaches — or if imaging came back “normal” but the pain persists — a consultation that looks at the full picture may be the missing piece.
