Why Does My Back Hurt More When I Sit Than When I Stand?

This is a question we hear often, and it comes down to how sitting changes the load and position of your spine compared to standing.

 What Happens to Your Spine When You Sit?
When sitting, particularly in a slouched position, the discs in your lower back experience increased pressure compared to standing. Sitting also tends to shorten the hip flexors over time, which can pull on the lower back and alter pelvic positioning — both of which can increase strain on lower back structures.

 Common Contributing Factors
Prolonged sitting without breaks, chairs that don't provide adequate lower back support, slouched posture (particularly when fatigued later in the day), and tight hip flexors from extended sitting that pull on the pelvis and lower back.

 What Can Help
Movement breaks — standing and walking briefly every 30-45 minutes helps reduce sustained pressure on the spine. Lower back support — a cushion or rolled towel can help maintain the natural curve of your lower back while seated. Hip flexor stretches — addressing tightness here can reduce strain on the lower back. Core strength — a stronger core helps support the spine during prolonged sitting.

 When to Get Checked
If sitting-related back pain is persistent, worsening, or affecting your ability to work or enjoy daily activities, an osteopathic assessment can identify the specific factors contributing to your pain — whether that's posture, muscle tightness, joint stiffness, or a combination — and create a plan addressing the root cause.
