Lower back and hip pain often show up together because the two areas share muscles, nerves, and connective tissue that work as a single system. Getting relief usually requires a combination of targeted stretching, strengthening the muscles that stabilize your pelvis and spine, adjusting how you sit and sleep, and knowing when the pain signals something more serious.
Why Your Back and Hip Hurt at the Same Time
A key player connecting these two areas is the psoas muscle, a long, ribbon-shaped muscle that runs from your lower back just below your ribs, through your pelvis, and attaches near the top of your thigh bone. You have one on each side of your spine. The psoas acts like a bridge between your upper and lower body, helping stabilize your posture and move your hips and legs. When it gets tight or irritated, often from prolonged sitting, it pulls on both the lumbar spine and the hip joint simultaneously.
This shared anatomy means the source of your pain isn’t always where you feel it. A stiff hip joint can force your lower back to compensate with extra movement, and a disc problem in your spine can send pain radiating into your hip or buttock. Accurate diagnosis relies on a thorough history, neurological assessment, and specific physical tests that isolate one area from the other. If your pain has persisted for more than a few weeks or keeps coming back, getting a professional evaluation helps you avoid spending months treating the wrong spot.
Stretches That Target Both Areas
Stretching the muscles that cross the lower back and hip can relieve tension on both sides of the problem. Focus on three muscle groups: the hip flexors (including the psoas), the piriformis deep in the buttock, and the hamstrings along the back of your thigh.
For the hip flexors, a kneeling lunge stretch works well. Drop one knee to the floor and step the other foot forward so your front knee is over your ankle. Gently shift your weight forward until you feel a stretch in the front of the hip on the kneeling side. Hold for 20 to 30 seconds, then switch. For the piriformis, lie on your back, cross one ankle over the opposite knee, and pull the bottom leg toward your chest until you feel a deep stretch in the buttock. The hamstrings respond to a simple standing or seated forward fold, keeping your back as flat as possible rather than rounding your spine.
Do each stretch on both sides, holding for 20 to 30 seconds, and aim for at least once daily. Consistency matters more than intensity. Forcing a stretch to the point of pain can tighten the muscle further.
Strengthening the Muscles That Stabilize You
Stretching alone won’t fix the problem if the muscles supporting your pelvis and spine are weak. Two muscle groups deserve the most attention: the deep core muscles that wrap around your trunk like a corset, and the gluteus medius, the muscle on the outer side of each hip that keeps your pelvis level when you walk or stand on one leg.
Research on chronic low back pain patients found that combining gluteal strengthening with lumbar stabilization exercises improved both muscle strength and balance. The key detail: exercises were performed with the lumbar spine held in a neutral position, not arched or flattened, to train the deep stabilizing muscles rather than the larger, more superficial ones. During the first three weeks, participants did each exercise 15 times per set, two sets per side, with no added resistance. From weeks four through six, they added resistance in the same positions.
Three exercises cover the essentials:
- Bridges. Lie on your back with knees bent and feet flat on the floor. Tighten your abdominal and buttock muscles, then raise your hips until your body forms a straight line from knees to shoulders. Hold long enough to take three deep breaths, then lower. Start with five repetitions a day and gradually build to 30.
- Bird-dogs. Start on hands and knees. Extend your right arm forward and left leg back simultaneously, keeping your hips level and your lower back still. Hold for a few seconds, return, and switch sides. This trains the deep core muscles to resist rotation.
- Side-lying leg raises. Lie on your side with your legs straight and stacked. Lift your top leg about 12 inches, keeping your hips stacked vertically so your pelvis doesn’t roll backward. This directly targets the gluteus medius. Start with 15 repetitions per side.
The progression matters. Start without resistance and focus on engaging the right muscles. Adding bands or ankle weights too early often leads to compensation from the lower back, which defeats the purpose.
How You Sit Matters More Than You Think
Sitting for long stretches compresses the lumbar discs and shortens the hip flexors, feeding the exact pattern that causes combined back and hip pain. A few adjustments to your workspace can reduce the load significantly.
Set your chair height so your feet rest flat on the floor and your thighs are parallel to it. This keeps your hips and knees at roughly a 90-degree angle, which distributes your weight more evenly across the pelvis. If your feet don’t reach the floor, use a footrest rather than letting your legs dangle. Place your monitor directly in front of you at arm’s length, with the top of the screen at or slightly below eye level. Looking down at a screen positioned too low encourages you to round your upper back, which shifts stress down to the lumbar spine.
Even with a perfect setup, static posture is the real enemy. Standing up and moving for even 30 to 60 seconds every half hour does more for your back and hips than the most expensive ergonomic chair.
Sleeping Positions That Reduce Strain
Poor sleep positioning can undo the progress you make during the day. The goal is to keep your spine, pelvis, and hips in neutral alignment throughout the night.
If you sleep on your side, draw your legs up slightly toward your chest and place a pillow between your knees. This keeps your pelvis from rotating and takes pressure off both the lower back and hip. A full-length body pillow works well if you tend to shift around. If you sleep on your back, place a pillow under your knees to relax the lower back muscles and maintain the natural curve of your lumbar spine. A small rolled towel under your waist provides additional support. Stomach sleeping puts the most stress on the lower back, but if you can’t sleep any other way, placing a pillow under your hips and lower abdomen reduces the strain.
Over-the-Counter Pain Relief
When the pain is interfering with your ability to exercise or sleep, short-term use of over-the-counter pain relievers can help you stay active while you address the underlying cause. A large Cochrane review found that both anti-inflammatory medications like ibuprofen and simple pain relievers like acetaminophen work better than placebo for acute low back pain, but the effect sizes are small. Anti-inflammatories were not meaningfully more effective than acetaminophen for pain relief, and they came with nearly twice the rate of side effects, mostly gastrointestinal.
Most clinical guidelines recommend trying acetaminophen first because of its better side effect profile. If that doesn’t provide enough relief, anti-inflammatories are a reasonable next step for short periods. Neither option is a long-term solution. Pain medication works best as a bridge that allows you to do the stretching and strengthening that actually resolves the problem.
Signs That Need Immediate Attention
Most combined back and hip pain is mechanical and responds to the strategies above. But a small number of cases involve nerve compression that requires urgent medical evaluation. The condition doctors worry about most is cauda equina syndrome, where a large disc herniation or other mass compresses the bundle of nerves at the base of the spine.
The warning signs are specific: numbness or tingling in the “saddle area” (the inner thighs, groin, buttocks, or the area that would contact a saddle), new difficulty controlling your bladder or bowels, significant weakness in one or both legs, or sudden onset of sexual dysfunction. Any combination of low back pain with bladder or bowel changes should be treated as a potential emergency until proven otherwise. This condition is rare, but delayed treatment can lead to permanent nerve damage.
