Why Does My Hip Hurt When I Lie Down? Causes and Solutions

Hip pain that worsens when lying down can disrupt your sleep and leave you exhausted. Understanding the cause helps you find relief and get the rest you need.

Common Causes of Hip Pain When Lying Down

Greater Trochanteric Bursitis

The most common cause of hip pain when lying down. The bursa on the outer hip becomes inflamed and painful when compressed.

What it feels like:

• Pain on the outer hip
• Worse when lying on that side
• Tender to touch over the hip bone
• May radiate down the outer thigh

What causes it:

• Weak hip abductors (glutes)
• Tight IT band
• Repetitive activities (running, cycling)
• Direct pressure from sleeping

Hip Arthritis

Arthritis can cause aching that worsens at rest, especially after a day of activity.

What it feels like:

• Deep aching in the hip or groin
• Stiffness after lying still
• Gradual onset over months/years
• Pain with hip movement

What causes it:

• Age-related wear and tear
• Previous injuries
• Genetics
• Excess body weight

Hip Labral Tears

The labrum lines the hip socket and can cause pain that's worse in certain positions.

What it feels like:

• Deep pain in the groin or front of hip
• Clicking or catching sensation
• Pain with certain leg positions
• May feel unstable

What causes it:

• Hip impingement over time
• Sports injuries
• Repetitive hip motion
• Hip structure variations

Piriformis Syndrome

The piriformis muscle in the buttock can tighten and cause pain that refers to the hip area, especially in certain sleeping positions.

What it feels like:

• Deep buttock pain
• May radiate down leg
• Worse with prolonged positions
• Tight sensation crossing legs

What causes it:

• Sitting for long periods
• Overuse from exercise
• Muscle imbalance
• Direct pressure when sleeping

Tendinitis

Hip flexor or gluteal tendinitis can cause pain that's noticeable at rest when inflammation is present.

What it feels like:

• Pain at front of hip (hip flexor) or outer hip (gluteal)
• Worse after activity
• Tender when pressing the area
• Stiffness after rest

What causes it:

• Overuse
• Sudden increase in activity
• Tight muscles
• Weakness in supporting muscles

How to Fix Hip Pain When Lying Down

1. Optimize Your Sleeping Position

Small changes can significantly reduce hip pressure.

For side sleepers:

• Place a firm pillow between your knees
• Keep knees slightly bent
• Try sleeping on the non-painful side
• Use a body pillow for full support

For back sleepers:

• Place a pillow under your knees
• Use a small pillow under your lower back if needed
• Keep legs slightly apart

For stomach sleepers (not ideal):

• Place a thin pillow under your pelvis
• Consider transitioning to side or back sleeping

2. Strengthen Your Hip Abductors

Weak hip muscles are the root cause of many hip problems.

Key exercises:

• Clamshells: Lie on side, lift top knee. 3 sets of 15 each side.
• Side-lying leg raises: Lift top leg toward ceiling. 3 sets of 15 each side.
• Standing hip abduction: Lift leg out to side with band. 3 sets of 15 each side.
• Single-leg bridges: Lift hips with one leg extended. 3 sets of 12 each side.

3. Stretch Tight Structures

Releasing tight muscles reduces pull on the hip.

Key stretches:

• IT band stretch: Cross leg behind, lean away. Hold 30 seconds each side.
• Piriformis stretch: Lie on back, cross ankle over knee, pull toward chest. Hold 30 seconds each side.
• Hip flexor stretch: Half-kneeling, push hips forward. Hold 30 seconds each side.
• Figure-4 stretch: Same as piriformis stretch. Hold 30 seconds each side.

4. Foam Roll the Outer Hip

Self-massage helps release tight fascia and muscles.

Technique:

• Lie on foam roller on outer hip/thigh
• Roll slowly from hip to knee
• Pause on tender spots for 30-60 seconds
• Roll for 2-3 minutes each side
• Use a tennis ball for deeper work on specific spots

5. Address Bursitis Specifically

If bursitis is the cause, targeted treatment helps.

Strategies:

• Avoid lying directly on the painful hip
• Ice for 15-20 minutes before bed
• Anti-inflammatory medication (consult doctor)
• Consider a mattress topper for pressure relief

6. Improve Daytime Habits

What you do during the day affects night pain.

Tips:

• Avoid prolonged sitting or standing
• Take movement breaks
• Stretch hip flexors if you sit a lot
• Avoid crossing your legs
• Strengthen hips during the day

When to See a Doctor

Seek professional evaluation if:

• Pain significantly disrupts sleep regularly
• You have groin pain with limited hip motion
• Pain is severe or rapidly worsening
• You have clicking, catching, or instability
• Symptoms don't improve after 3-4 weeks
• Pain is accompanied by fever

Prevention Strategies

Build habits:

1. Strengthen hip abductors regularly
2. Stretch hip flexors and IT band daily
3. Use proper sleeping position and pillow
4. Stay active during the day
5. Avoid prolonged static positions
6. Maintain healthy body weight

The Bottom Line

Hip pain when lying down usually stems from bursitis, tight structures, or underlying joint issues. The fix combines optimizing your sleeping position, strengthening weak hip muscles, stretching tight structures, and addressing inflammation.

Start with the sleeping position modifications and pillow between the knees—these often provide immediate relief. Add the hip strengthening and stretching for long-term improvement. Most people see significant improvement within 3-4 weeks of consistent effort.

If pain is severe, involves the groin, or limits your hip motion, see a healthcare provider for proper evaluation.
