Hip pain or back pain? How to tell them apart

Hip pain and lower back pain sit close enough together, and share enough overlapping nerve pathways, that it’s genuinely common to be confused about which one is actually the problem. Someone will describe “hip pain” that turns out, on examination, to be coming entirely from the spine — or the reverse, back pain that’s really a hip joint issue referring pain upward.

Getting this right matters because the treatment is completely different depending on which joint is actually responsible.

Where the pain is felt — a useful but imperfect clue

Pain over the bony point at the side of the hip — the part you’d feel if you rested a hand on your hip pocket — more often points to the hip joint itself, or to the soft tissue and tendons around it.

Pain centred in the lower back, or deep in the buttock, more often originates from the spine — commonly a joint, disc, or nerve in the lower back.

Pain that runs down the back or side of the leg, particularly past the knee, and especially with any numbness or tingling, strongly suggests a nerve being irritated in the spine rather than a hip joint problem, even if it’s felt partly around the hip area on its way down.

This is a useful starting point, but it isn’t reliable enough to diagnose from alone — referred pain can genuinely mimic the other joint closely enough to fool most people, which is exactly why this confusion is so common.

What makes it worse — often more telling than where it hurts

Hip joint problems tend to flare with movements that specifically load or rotate the hip: putting on socks or shoes, getting in and out of a low car, crossing the legs, or turning the leg inward or outward. Pain that’s sharply worse with these specific movements, more than with back movements, points toward the hip.

Spinal problems tend to flare with movements of the back itself: bending forward, twisting the torso, prolonged sitting, or standing up from a seated position. If those are what reliably bring the pain on, the spine is the more likely source.

When the spine causes hip-area pain directly

A nerve root irritated in the lower spine — from a herniated disc or spinal stenosis, for example — can refer pain into the buttock and outer hip through shared nerve pathways, even though the hip joint itself is entirely healthy. This is a genuinely common source of diagnostic confusion, and it’s one reason people sometimes pursue hip treatment for months before the actual spinal cause is identified.

Sacroiliac joint dysfunction — a problem with the joint connecting the base of the spine to the pelvis — sits almost exactly between the two areas anatomically and is another frequent source of pain that gets mistaken for either a hip or a lower back problem.

When they genuinely coexist

It’s not always one or the other. A long-standing hip problem changes how you walk and stand, which can place additional strain on the lower back over time — and the reverse is equally true. In these cases, treating only one joint often leaves some pain unresolved, because both are genuinely contributing.

Getting an accurate diagnosis

A clinical examination that specifically tests hip movements against spine movements is usually the most informative first step, and it’s something a clinician can do in a single visit. From there, imaging of the hip, the spine, or both may be appropriate depending on what the examination suggests.

Sometimes a targeted diagnostic injection — placing a small amount of anaesthetic directly into the joint suspected of causing the pain — is used specifically to confirm the source, since clear relief after the injection is a strong indicator that joint was responsible.

If you’ve been treating what you assumed was a hip problem without real improvement, or the reverse, it’s worth a fresh assessment that specifically considers both joints rather than continuing to treat an assumption. A spine consultation that includes a hip examination can settle the question directly rather than leaving you guessing.
