Back Stiffness

Overview

Back stiffness is a feeling of tightness or reduced motion in the lower back — common after sitting, first thing in the morning, or after a period of reduced activity.

Stiffness is usually a load-and-movement problem rather than a sign of damage. The back stiffens when it has been still, and it usually loosens with movement.

What This Symptom Feels Like

• Tightness when rising from sitting or getting out of bed
• Morning stiffness that eases within minutes of moving
• Difficulty bending or twisting fully
• Aching that loosens up with activity
• Stiffness that returns after long periods of sitting

Common Causes

• Low back strain — stiffness is common as a strain settles
• General load-related stiffness after prolonged sitting or a new activity
• Lumbar spinal stenosis — can include stiffness with leg symptoms
• Simply less movement than usual — stiffness follows stillness

Anatomy Usually Involved

• Lumbar spine — the lower vertebrae, discs and facet joints

Questions to Ask Yourself

• Is the stiffness worse in the morning, after sitting, or after activity?
• How long does it take to loosen up?
• Is there leg pain, numbness or weakness?
• Has your activity level or sitting time changed recently?
• Is motion steadily decreasing?

When It's Usually Minor

Morning stiffness that eases within minutes and tightness after sitting that resolves with movement are common and respond well to regular movement.

When To Seek Medical Care

• Stiffness with leg numbness, weakness or changes in bladder or bowel function
• Stiffness that follows major trauma
• Stiffness that is steadily worsening and limiting daily life
• Stiffness with fever, chills or unexplained weight loss

Self-Care Options

• Move regularly throughout the day — short, frequent movement beats long sessions
• Stand, walk or change position during long sits
• Gentle bending and stretching within comfort
• Keep strengthening the trunk and hips
• Avoid prolonged rest, which makes stiffness worse

Related Symptoms
