How to Help Lower Back and Hip Pain: Causes and Relief

Lower back pain and hip pain frequently travel together because the two regions share muscles, nerves, and mechanical load in ways that make it hard to tell where one problem ends and the other begins. In a study of 200 patients referred for low back pain, only about two-thirds turned out to have a spine-only problem; roughly one in five had some combination of spine, hip, and sacroiliac joint involvement, and about one in twelve had hip or sacroiliac joint pathology with no spinal source at all.¹ That overlap shapes everything from diagnosis to treatment. Getting better usually means addressing both areas rather than chasing one spot on the body.

Why Lower Back and Hip Pain So Often Show Up Together

Your lumbar spine, pelvis, and hips form a single mechanical chain. When you walk, bend, or twist, forces pass through all three regions, and a change in one area shifts the demands on the others. The sacroiliac joint, which sits between the base of the spine and the pelvis, is a common crossover point. Sacroiliac joint dysfunction is increasingly recognized as an underappreciated source of low back pain.² Among patients who already have a lumbar disc herniation, roughly a third also test positive for sacroiliac joint dysfunction on clinical provocation tests, and those patients tend to report pain spreading into the leg.³

Degeneration in one joint can also accelerate wear in the other. A cadaveric study found that hip arthritis was a stronger predictor of lumbar spine arthritis than knee arthritis was, and the relationship worked in reverse as well: spine arthritis predicted hip arthritis more strongly than knee arthritis did.⁴ Clinicians sometimes call this reciprocal breakdown “hip-spine syndrome,” and it explains why people with a severely arthritic hip often develop worsening back pain, and vice versa.

Sorting Out the Source of Pain

Because so many structures overlap in this area, pinning down the actual pain generator matters before jumping to treatment. Here are some of the most common causes, grouped by what is actually producing the symptoms.

Nerve Irritation and Radiculopathy

A compressed or inflamed nerve root in the lumbar spine can send pain radiating down through the buttock and hip and into the leg. This happens most often with a disc herniation or spinal stenosis, and the pain typically follows a specific pathway that corresponds to the nerve involved.⁵ People often describe it as a deep, shooting sensation that worsens with certain positions like sitting or bending forward. Numbness, tingling, or weakness in the foot or leg can accompany the pain.

Piriformis syndrome produces a similar pattern but from a different location. The piriformis is a small muscle deep in the buttock, and when it compresses or irritates the sciatic nerve, the result mimics a lumbar disc problem.⁶ Anatomical variations in how the sciatic nerve passes through or around the piriformis muscle can make some people more susceptible.⁷ The practical distinction matters because piriformis syndrome responds well to targeted stretching and manual therapy, whereas a large disc herniation may need a different approach entirely.

Gluteal Tendinopathy

If the pain is concentrated on the outside of your hip and possibly creeps into the lower back, the tendons of the gluteus medius and gluteus minimus muscles are a likely culprit. This condition, once lumped under the vague label of “trochanteric bursitis,” is now understood to be primarily a tendon problem rather than inflammation of a bursa.⁸ It is most common in middle-aged women, although athletes of any sex can develop it too.⁹ The hallmark complaint is pain when lying on the affected side at night, along with difficulty climbing stairs or standing on one leg.¹⁰

Pelvic Alignment and Muscle Imbalance

Excessive anterior pelvic tilt, where the front of the pelvis drops forward and the lower back arches more than it should, has a statistically significant association with low back pain, though the relationship is modest.¹¹ Tight hip flexors and weak glutes are the usual drivers. This tilt changes how force is distributed across the lumbar discs and the hip joints, and over time that redistribution can provoke pain in both places. Correcting it is less about achieving some “perfect” posture and more about restoring enough flexibility and strength so your pelvis can move freely in multiple directions.

Exercise-Based Approaches That Help

Movement is the single most consistently supported intervention for combined lower back and hip pain. The specific type of exercise matters less than you might expect; what matters more is that you do it regularly and progressively.

Core Strengthening

Training the muscles that stabilize your trunk, including the deep abdominals, the multifidus along the spine, and the pelvic-floor muscles, has strong evidence behind it. A systematic review comparing core training methods to conventional resistance training found that core-focused approaches were more effective at reducing chronic low back pain across several measurement scales.¹² A review of core stability programs for athletes with low back pain found that most studies reported significant pain improvements, particularly when exercises progressed from basic cocontraction of deep muscles to more complex positions using unstable surfaces.¹³

Practical starting points include the dead bug, bird dog, and side plank. These all train the trunk to resist unwanted movement while the limbs are working, which is what your core actually does during daily life. Once those feel manageable, adding load or instability, such as performing exercises on a balance pad, drives further adaptation.

Directional Preference and Movement-Based Therapy

The McKenzie method classifies low back pain by how it responds to specific movements, typically repeated extensions or flexions, and then prescribes exercises in the direction that reduces symptoms. Evidence for its use in chronic low back pain is limited overall.¹⁴ However, when patients are selected based on having a clear “directional preference,” meaning their pain clearly worsens or improves with a specific movement direction, the McKenzie approach performs comparably to motor control exercises, with a slight edge in perceived recovery.¹⁵ Adding manual therapy on top of McKenzie exercises can help reduce pain, but does not appear to offer a meaningful additional benefit beyond what the exercises achieve on their own.¹⁶

The takeaway for someone dealing with combined back and hip pain is worth paying attention to which movements make things better or worse. If extending your spine provides relief, leaning into that direction through repeated press-ups or standing back bends can be a useful self-management tool. If flexion feels better, stretching into a child’s pose or pulling your knees to your chest may help more. The direction is individual, not universal.

Medications and Injections

For acute flare-ups, over-the-counter anti-inflammatory drugs like ibuprofen and naproxen have good evidence for pain relief in both acute and chronic low back pain, with moderate effect sizes, typically reducing pain by about 10 to 20 points on a 100-point scale.¹⁷ Muscle relaxants can help during an acute episode, and combining them with an NSAID appears to produce somewhat better pain relief and tolerability than an NSAID alone.¹⁸ For chronic pain that does not respond to standard anti-inflammatories, tricyclic antidepressants at low doses show a small to moderate benefit.¹⁷

When pain radiates into the leg and conservative measures have not helped, epidural steroid injections are an option. A meta-analysis found strong evidence that epidural injections with local anesthetic plus steroids provide meaningful relief for lumbar radiculopathy, and moderate to strong evidence that local anesthetic alone can also help.¹⁹ These injections are typically used as a bridge, reducing pain enough for physical therapy and exercise to gain traction, not as a standalone fix.

Dry Needling, Acupuncture, and Complementary Options

Dry needling, which involves inserting thin needles into muscular trigger points, has gained popularity for low back pain. A meta-analysis found that it was more effective than sham needling for reducing pain intensity both immediately after treatment and at follow-up.²⁰ Another review focusing specifically on trigger-point dry needling found moderate evidence supporting its use for low back pain intensity, especially when combined with other therapies like exercise or manual therapy.²¹

Acupuncture, the more established cousin, shows a pattern that is consistent but underwhelming in isolation. A large Cochrane review of 35 trials found that acupuncture was more effective than no treatment or sham treatment for chronic low back pain in the short term, but was not more effective than other conventional or alternative treatments used alone. The most promising finding was that adding acupuncture to an existing treatment plan produced small improvements in pain and function beyond what the existing plan achieved by itself.²² Neither acupuncture nor dry needling had sufficient evidence for acute low back pain.

The Role of Fear, Beliefs, and Stress

The psychological side of back and hip pain does not get enough attention outside of specialist clinics, but it can make or break recovery. Fear-avoidance beliefs, the conviction that movement will cause further injury or that your spine is fragile, consistently delay healing and increase disability.²³ These beliefs arise from a combination of past painful experiences and well-meaning but inaccurate information, things like being told your disc is “slipping” or that you should avoid bending. The result is a cycle where fear leads to avoidance of movement, avoidance leads to deconditioning, and deconditioning leads to more pain.

Mindfulness-based stress reduction (MBSR), an eight-week program of meditation and body awareness, has been tested head-to-head against cognitive behavioral therapy (CBT) and usual care for chronic low back pain. At six months, about 61% of the MBSR group and 58% of the CBT group showed clinically meaningful improvement in function, compared to 44% of the usual-care group. For pain specifically, about 44% in MBSR and 45% in CBT improved meaningfully, versus 27% in usual care. The benefits of MBSR persisted through a full year of follow-up.²⁴ This does not mean the pain is “in your head.” It means your nervous system’s interpretation of danger signals can be recalibrated through structured psychological techniques, and the effect is clinically real.

Lifestyle Factors That Make a Practical Difference

Sitting and Spinal Loading

Prolonged sitting is widely blamed for back pain, and there is a biomechanical basis for the concern, though the relationship is more nuanced than “sitting is bad.” A comprehensive review of intradiscal pressure studies found that at back flexion angles less than 20 degrees, pressure on the lumbar discs is greater when sitting than when standing. However, once the flexion angle exceeds about 20 degrees, the relationship reverses.²⁵ Adding load, like holding heavy objects while seated and slightly bent, ramps disc pressure sharply. The practical implication: if you sit for long stretches, keeping some lumbar support behind your lower back and taking regular movement breaks can reduce the cumulative load on your discs. Slouching with a rounded lower back at a desk is a particularly high-load posture for the lumbar spine.

Your Mattress

If your back and hip pain is worse in the morning, your mattress is worth examining. A randomized controlled trial in patients with chronic nonspecific low back pain found that medium-firm mattresses produced significantly better outcomes for pain and disability compared to firm mattresses over 90 days. Patients on medium-firm mattresses had less pain while lying in bed, less pain upon rising, and lower disability scores.²⁶ The old advice to sleep on the firmest mattress you can find is not supported by the evidence.

Body Weight and Metabolic Health

Excess body weight loads the spine and hip joints continuously, but the relationship between weight and back pain goes beyond simple mechanics. A genetic analysis found that metabolic syndrome, a cluster of conditions including increased waist circumference, elevated blood sugar, and abnormal cholesterol, mediated a meaningful portion of the link between lower educational attainment and both disc degeneration and low back pain. Waist circumference alone accounted for a notable share of this effect.²⁷ This suggests that systemic inflammation and metabolic dysfunction contribute to disc breakdown, not just mechanical compression from carrying extra weight. Addressing metabolic health through diet and exercise may protect your discs and joints in ways that go beyond just reducing the load.

When Surgery Enters the Picture

Surgery is rarely the first option for combined back and hip pain, but when severe arthritis in one joint is driving pain in the other, the question of which to address first becomes important. A study of patients with severe hip osteoarthritis who underwent total hip replacement found that both hip pain and low back pain improved significantly after surgery. Average back pain scores dropped meaningfully and disability scores improved, with results maintained at two-year follow-up.²⁸

Sequencing matters. A large outcomes study comparing patients who had hip replacement first versus lumbar spine surgery first found that those who underwent hip replacement first were much less likely to need a subsequent spinal procedure (about 6% versus 24%). Patients who had spine surgery first also had higher rates of hip dislocation when they later underwent hip replacement, and those who had spine surgery only used significantly more opioids at one year than any other group.²⁹ If both your hip and spine are candidates for surgery, discussing the order with an orthopedic surgeon who understands hip-spine relationships is worth the effort.

Red Flags That Mean You Should Not Wait

Most combined back and hip pain is mechanical and manageable with the approaches described above. But certain symptoms suggest something more serious is going on and require urgent medical evaluation. An emergency department study calculated which “red flags” were most predictive of serious underlying conditions. The following signs stood out as strongly associated with serious spinal pathology:

Saddle anesthesia: numbness in the area that would contact a saddle, covering the inner thighs and groin
Loss of bowel or bladder control: new inability to control urination or defecation, or difficulty starting urination
Progressive leg weakness: rapidly worsening ability to lift the foot or push off when walking
Fever with back pain: this was the strongest single predictor of serious pathology in the emergency department data
Unexplained weight loss: significant unintentional weight loss combined with back pain raises concern for malignancy or infection

Saddle anesthesia and loss of anal sphincter tone had high positive likelihood ratios for serious spinal pathology specifically, indicating cauda equina syndrome, which requires emergency surgical intervention.³⁰ When bowel and bladder dysfunction and saddle numbness occur together, the probability of spinal cord compression increases further.³¹ If you experience any of these, get to an emergency department rather than scheduling a routine appointment.

How the Spine Got Here in the First Place

It helps to understand that the human spine was not designed by an engineer. Bipedal walking is a relatively recent adaptation in evolutionary terms, and the lumbar curve that allows us to stand upright also concentrates tremendous force on a small number of segments. A visual analysis of how human spinal posture has changed over evolutionary time highlights a biomechanical mismatch: the spine that evolved for a mix of climbing, walking, and foraging now spends hours locked into sedentary postures it was never adapted for.³² This does not mean your back is inevitably fragile, far from it. But it does explain why the lower back and hips are vulnerable to the specific demands of modern life: prolonged sitting, repetitive loading, and sudden heavy lifts. The spine handles variety and movement well. It handles stagnation poorly. Building your daily routine around that fact is probably the single most useful thing you can take from the research.
