Coccyx Pain vs Sciatica: Key Differences & Treatment

Reviewed by: Dr. Sarah Mitchell, MD | Updated: March 2026

Lower back and buttock pain can be confusing. Is it your tailbone or your sciatic nerve? Getting the right diagnosis is crucial for effective treatment. This guide breaks down the key differences.

Quick Comparison

🔵 Coccyx Pain (Coccydynia)

Pain at base of spine
Worse when sitting
Better when standing/walking
Localized tenderness
Usually from trauma or sitting

🔴 Sciatica

Pain radiates down leg
Worse with coughing/sneezing
Numbness/tingling common
Lower back to foot pain
From herniated disc or stenosis

Detailed Symptom Comparison

Feature	Coccyx Pain	Sciatica
Pain Location	Base of spine, between buttocks	Lower back, buttock, down leg
Pain Pattern	Localized, sharp or achy	Radiating, shooting, burning
Sitting	Much worse	May help or worsen
Standing	Usually better	Variable
Walking	Usually comfortable	May worsen with walking
Numbness	Rare	Common in leg/foot
Weakness	No	Possible in leg/foot

Can You Have Both?

Yes, it's possible to have both conditions simultaneously. Chronic coccyx pain can alter your posture and gait, potentially contributing to lower back strain. Conversely, severe sciatica may cause you to sit awkwardly, putting pressure on the coccyx.

When to See a Doctor

Seek medical evaluation if you have:

Severe pain lasting more than 2 weeks
Numbness or weakness in leg
Loss of bowel or bladder control
Pain that worsens despite rest
Difficulty distinguishing the source

Getting the Right Diagnosis

Your doctor may use:

Physical exam: Specific tests differentiate the two
X-ray: Shows coccyx abnormalities
MRI: Reveals disc herniation or spinal stenosis
Diagnostic injection: Numbs specific nerves to pinpoint source
