Advice

Pain in the deep buttocks and lower back is a common complaint, often affecting people of all ages and lifestyles. It can range from a dull ache to sharp, radiating discomfort that interferes with sitting, walking, or daily activities. Understanding what causes this type of pain is the first step toward finding relief.

Common Causes of Deep Buttock & Lower Back Pain

Several conditions can lead to discomfort in both areas. Here are the most frequent causes…

Piriformis Syndrome

The piriformis muscle, located deep in the buttocks, can become tight or inflamed and press on the sciatic nerve, causing pain that may radiate to the lower back and down the leg.

Symptoms

• Deep aching in the buttocks
• Pain that worsens when sitting
• Tingling or numbness down the leg

Sciatica

Sciatica occurs when the sciatic nerve is irritated, often due to a herniated disc or spinal stenosis. Pain can begin in the lower back and shoot through the buttocks and down one leg.

Symptoms

• Sharp, shooting pain
• Numbness or burning sensations
• Pain on one side of the body

Sacroiliac (SI) Joint Dysfunction

The SI joints connect the spine to the pelvis. If they become inflamed or misaligned, they can cause lower back and buttock pain.

Symptoms

• Aching near the tailbone and hips
• Pain when standing or transitioning from sitting
• Limited mobility in the lower back

Herniated or Bulging Disc

When a disc in the lower spine presses on nearby nerves, it can cause referred pain in both the back and buttocks.

Symptoms

• Lower back stiffness
• Shooting pain when bending or lifting
• Possible leg weakness

Muscle Strain or Overuse

Straining the glutes or lower back muscles through exercise, lifting, or prolonged sitting can lead to soreness and tightness in both regions.

Symptoms

• Tenderness in the lower back or buttocks
• Pain that worsens with movement
• Muscle spasms

When to See a Doctor

Seek medical attention if your pain…

• Lasts more than a few weeks
• Radiates below the knee
• Is accompanied by numbness or weakness
• Interferes with bladder or bowel control

These may be signs of a more serious issue like nerve compression or spinal conditions.

Gentle Ways to Relieve Pain

• Stretching – Gentle stretches for the piriformis, hamstrings, & lower back
• Heat/Ice Therapy – Helps reduce inflammation and muscle tension
• Posture Correction – Avoid slouching and use ergonomic seating
• Physical Therapy – A personalized plan can improve strength and mobility

Pain in the deep buttocks and lower back is usually treatable, especially when the cause is identified early. It may be muscle strain, sciatica, or joint dysfunction, a combination of gentle movement, targeted therapy, & lifestyle changes can make a big difference.
