Sacrum pain occurs in the triangular bone at the base of the spine, just above the tailbone. While it can feel similar to general lower back pain, it has its own specific causes and treatment considerations.
What Is the Sacrum?
The sacrum is formed by five fused vertebrae, sitting between the lumbar spine and the coccyx. It connects to the pelvis via the sacroiliac joints on either side.
Common Causes of Sacrum Pain
- Sacroiliac joint dysfunction: Irritation or instability where the sacrum meets the pelvis
- Sacral stress fractures: Can occur from repetitive impact or in those with reduced bone density
- Pregnancy: Hormonal changes and shifting posture can stress this area
- Referred pain: Issues in the lower lumbar spine can sometimes be felt in the sacral region
- Prolonged sitting: Particularly on hard or unsupportive surfaces
Symptoms of Sacrum Pain
- Dull, aching pain at the base of the spine, above the tailbone
- Pain that may radiate into the buttocks or upper thighs
- Discomfort that worsens with prolonged sitting or standing
- Stiffness, especially after periods of inactivity
How to Relieve Sacrum Pain
- Gentle stretching: Targeting the hips, glutes, and lower back
- Pelvic stabilization exercises: Build supportive strength around the sacrum and pelvis
- Supportive seating: Cushions designed to reduce pressure on this area
- Heat or ice therapy: Depending on whether muscle tension or inflammation is the primary issue
When to See a Doctor
If sacrum pain is severe, persistent, or follows an injury, a healthcare provider can evaluate for fracture, joint dysfunction, or other underlying causes through physical examination and, if needed, imaging.
The Bottom Line
Sacrum pain often stems from the sacroiliac joints or surrounding muscles, and it typically improves with targeted stretching, stabilization exercises, and supportive seating.
