Back Stiffness
Back stiffness is a condition where there is a hard or rigid feeling throughout the spine that makes movement difficult.

Symptoms
Back stiffness affects people of all ages — from teenagers to older adults — making it one of the most universally experienced spinal complaints. It can cause a heavy, tight sensation in the back, reduce range of motion, and make simple tasks like bending or turning painful.
Depending on cause & location, you may also experience:
Morning stiffness that is worst on waking and gradually eases with movement
Pain that worsens with prolonged rest, sitting, standing, or walking
Heavy or restricted movement in the back, neck, legs, feet, hands or fingers
Pain that comes and goes, often triggered by certain postures or movements
Muscle spasms or tightness alongside the spine after sudden movement
Difficulty bending, twisting, or straightening up fully from a bent position
