Why does facet joint syndrome cause lower back pain?

Facet joint syndrome causes lower back pain when irritated joints and their surrounding tissues send pain signals during loading, bending, or rotation. Lower Back Pain is a common presentation of Facet Joint Syndrome. Pain may remain close to the spine and can worsen when leaning backward, standing for a long time, or turning.

Facet joints connect the small bones of the spine and help control its movement. Irritation in a joint lining or nearby capsule can make normal pressure feel painful. Muscles around the spine may then tighten, adding soreness and reducing comfortable movement. Facet-related pain can be felt on one side or both sides and may spread into the buttock or upper thigh without following a single nerve path. Similar pain can come from discs, muscles, hips, or nerves, so the location alone cannot establish the cause.

Change position regularly, use short walks, and keep daily movement within a tolerable range. Temporarily reduce repeated back extension, twisting, or heavy lifting if these clearly provoke symptoms. A physiotherapist can work on trunk and hip control, mobility, and gradual strengthening rather than relying only on rest. Heat may ease muscle guarding for some people. A healthcare professional can help choose pain relief that is appropriate for your medical history.

Seek an assessment if pain is persistent, recurrent, or stopping you from sleeping, working, or walking normally. Get urgent help for new loss of bladder or bowel control, numbness around the inner thighs, progressive leg weakness, fever, or severe pain following major trauma.

Ask what findings support facet joint involvement, which movements to modify, and how to progress exercise. Discuss whether leg symptoms or neurological changes suggest another source that needs prompt review.
