What Causes Hip Pain That Radiates Down the Leg at Night

Nighttime hip pain that radiates down the leg can be an incredibly frustrating and disruptive issue. Many people find themselves tossing and turning, unable to get a good night’s sleep due to persistent discomfort. What causes hip pain that radiates down the leg at night is a question commonly asked by patients seeking relief. This pain isn’t just inconvenient—it may be a sign of underlying health concerns that require attention. Disturbed sleep, nighttime-only hip pain, and pressure points from poor posture can aggravate the condition.

Understanding the Nature of Radiating Hip Pain

Hip pain radiating down leg to foot is often a result of complex musculoskeletal or neurological conditions. Radiating hip pain refers to discomfort that begins in the hip area and travels down the leg, sometimes reaching the foot. It can present as sharp, dull, burning, or throbbing and may vary in intensity. What causes hip pain that radiates down the leg often relates to nerve compression, muscle imbalance, or inflammation.

Nighttime symptoms can differ significantly from those experienced during the day. During rest, certain positions or pressure points may aggravate inflamed tissues or compressed nerves, making hip pain radiating down leg to foot more intense while trying to sleep.

A study by Washington University School of Medicine found that younger and middle-aged adults dealing with hip pain experienced notably higher rates of insomnia and anxiety compared to those without hip pain. This highlights the significant connection between ongoing hip discomfort and mental health challenges, especially sleep disturbances. Sleep position, supportive mattress, or lack of appropriate footwear can further influence symptoms. Pregnancy hormone changes and added pressure on the abdomen in pregnant women also contribute to pelvic pain in pregnancy and mobility issues during pregnancy.

Common Causes of Hip Pain That Radiates at Night

Many individuals want to know what causes hip pain that radiates down the leg at night, especially when it becomes persistent. The answer isn’t always simple. Multiple underlying health issues can lead to nighttime pain, from joint and nerve problems to muscular or structural damage. Here’s a breakdown of the most common culprits:

Sciatica

Sciatica is a common condition caused by irritation or compression of the sciatic nerve, often due to a herniated disc or bone spurs. This nerve travels from the lower back through the hips and down each leg. Pain from sciatica often worsens at night due to pressure on hips and spine, improper sleep position, or piriformis muscles tightening during rest. In some cases, sciatic-piriformis syndrome or compression of sacral nerve roots can amplify tingling, numbness, or muscle weakness.

Hip Osteoarthritis

Osteoarthritis involves the gradual degeneration of cartilage in the hip joint, causing pain, reduced range of motion in the hips, and stiffness. At night, lack of movement leads to inflammation and swelling, triggering hip pain radiating down leg. This condition may also be accompanied by bone spurs and ligaments and muscles loosening, which worsen during rest.

According to research conducted by Johns Hopkins University, nearly 14.3% of individuals aged 60 and above reported experiencing moderate to severe hip pain on most days over a six-week timeframe. Interestingly, the findings also indicated that women were more prone to report this type of chronic discomfort than men. This highlights how common degenerative joint conditions are in aging adults and emphasizes the need for timely diagnosis and treatment.

Bursitis

Trochanteric bursitis and iliopsoas bursitis are forms of bursitis that involve inflammation of the fluid-filled sacs that cushion the hip. Lying on the affected side during sleep creates pressure, resulting in sharp pain. Greater trochanteric pain syndrome and greater trochanter pain syndrome are overlapping conditions that also manifest as lateral hip pain.

Labral Tear

A hip labral tear involves damage to the cartilage ring around the hip socket. This can cause hip dislocation, pain in the hip or pelvis, and hip pain radiating down leg. Prolonged inactivity or side-sleeping increases irritation. Diagnostic tests like MRIs help detect these tears and guide treatment.

Hip Impingement (FAI)

Hip impingement or femoroacetabular impingement results from abnormal contact between the hip bones. The friction leads to labral tear, pain, and stiffness. Nighttime rest in certain positions can increase pressure and limit circulation, intensifying symptoms.

Muscle Strains or Tendon Injuries

Conditions such as hip flexor strains, gluteal tendinopathy, tendinitis, and general tendinopathy stem from overuse, trauma, or poor mechanics. These conditions often become more apparent at night due to delayed inflammation. Targeted exercise and stretching, along with compression shorts, may ease symptoms.

Greater Trochanter Pain Syndrome

Often misdiagnosed, greater trochanteric pain syndrome involves chronic pain over the outer hip. It worsens when sleeping on the affected side, especially for side sleepers. This syndrome may result from muscle imbalance, weak core muscles, or repetitive strain.

External Snapping Hip Syndrome

External snapping hip involves tendons flicking over bony structures, creating irritation and snapping sensations. This snapping often causes sharp pain, particularly when transitioning in and out of sleep positions. Related tendon inflammation can result in hip pain radiating down leg.

Sleeping Position

Improper sleep position or poor mattress quality can cause hip alignment issues. Using a pillow between knees or investing in a mattress topper, foam topper, or supportive mattress may alleviate pressure on nerves and joints. Pregnant individuals may benefit from a pregnancy pillow to reduce pressure on hips and spine.

Endometriosis (for Female Patients)

Endometriosis can mimic musculoskeletal pain by causing deep pelvic pain in pregnancy, hip discomfort, and radiating leg symptoms. The presence of endometrial tissue outside the uterus can lead to hip pain radiating down leg and worsen at night due to hormonal fluctuations.

Hip Fracture (Especially in Older Adults)

A hip fracture may not always be obvious but can cause severe pain at night. Symptoms include the inability to bear weight on your affected leg, can’t move your leg or hip, or the appearance of a deformed joint. Immediate evaluation and diagnostic tests are necessary for these red flags.

How to Describe Hip Pain That Radiates

Understanding and communicating the nature of your pain is crucial. Common descriptors include:

Sharp or stabbing – may indicate nerve compression or sciatic nerve involvement.
Dull or aching – often linked with osteoarthritis, bursitis, or tendinopathy.
Burning or tingling – typical of sciatica, sciatic-piriformis syndrome, or pinched nerve in the hip.
Positional – pain worsens in certain sleep positions or during pressure points contact.

These distinctions are important to differentiate between joint disorders, ligament strain, or nerve-related causes like lumbar nerve roots compression.

How to Relieve Hip Pain at Night

There are several lifestyle and therapeutic measures that may ease nighttime hip discomfort. These strategies are often simple yet highly effective. Understanding the cause of what causes hip pain that radiates down the leg at night is essential for targeting the right treatment.

Try Better Sleep Positions

Avoid lying on the painful side. Sleeping on your back with a pillow between legs or under the knees can reduce hip alignment issues and minimize pressure on hips and spine. Sleep position during pregnancy is particularly important to address pelvic pain in pregnancy.

Use Pillows for Support

A pillow between knees, foam topper, or pregnancy pillow can significantly reduce pressure on hip joints. These tools help maintain proper posture and prevent excessive stress on the iliotibial (it) band and gluteal tendons.

Apply Ice or Heat Before Bedtime

Use hot packs or ice packs for 15–20 minutes before bed. Ice reduces inflammation in conditions like bursitis, while heat relieves tight muscles and tendinopathy. Both can reduce hip pain radiating down leg to foot.

Gentle Stretching or Mobility Exercises

Practices like hip flexor stretches, clamshells, side or back leg lifts, and resistance band routines can improve mobility and alleviate pain. These low-impact exercises support core strengthening, prevent muscle imbalance, and enhance recovery.

When to See a Healthcare Provider

It’s important to recognize when pain requires professional attention. Some signs point to serious conditions that demand immediate evaluation. If you’re unsure what causes hip pain that radiates down the leg at night, look for these red flags:

Numbness and tingling in the affected leg or foot
Muscle weakness in the leg or inability to walk
Loss of bladder or bowel control
Deformed joint or visible swelling
Persistent hip pain, severe hip pain, or sudden swelling of your hip
Signs of infection such as fever or redness

These may indicate a hip fracture, herniated disc, or labral tear.
