What back pain and sciatica actually are
Most lower back pain is called non-specific, which means it comes from the joints, discs, muscles and ligaments of the spine rather than from serious damage. Sciatica is different. It is leg pain caused by an irritated nerve root in the lower back, usually felt in the buttock and down the leg, often below the knee.
- A dull ache or stiffness across the lower back, often worse after long spells of sitting or first thing in the morning
- Sharp, burning or electric pain travelling down one leg, sometimes with tingling or numbness in the foot
- Flare-ups after lifting, gardening, a long drive or a sudden jump in activity
- Pain that eases once you get moving and returns when you stay in one position for too long
