Can lumbar spondylosis cause sciatica?

Disc height loss, bony overgrowth, and thickened joints or ligaments can reduce the room available around a spinal nerve. However, lumbar spondylosis may also exist without leg symptoms, so an examination is needed to connect scan findings with what you feel.

Sciatica describes nerve-related symptoms that travel from the lower back or buttock into the leg. The sensation may be burning, electric, sharp, tingling, or numb, and coughing or certain spinal positions can aggravate it. Some people also notice weakness in part of the leg or foot.

Pain confined to the lower back is not the same as sciatica. A clinician checks the distribution of symptoms, muscle strength, sensation, and reflexes to judge whether a nerve root is involved and whether another hip, joint, or peripheral nerve problem could explain the pattern.

Stay gently active and change positions regularly rather than remaining in bed. Short walks and comfortable movements are often easier to tolerate than prolonged sitting or repeated bending during a flare. Stop an exercise if it causes new weakness or substantially spreads symptoms farther down the leg.

Physiotherapy may address movement, strength, activity pacing, and ways to reduce nerve irritation. A medical review is appropriate when symptoms persist, repeatedly return, disturb sleep, or interfere with walking and work. Imaging is not required for every episode, but it may help when findings could alter treatment.

Seek emergency care for new loss of bladder or bowel control, numbness around the genitals or inner thighs, or severe symptoms affecting both legs. These can indicate major pressure on the nerves at the base of the spine.

Get urgent medical advice for new or worsening leg weakness, a foot that starts dragging, fever with severe back pain, or pain following significant trauma. Prompt assessment is also sensible when you feel generally unwell alongside rapidly escalating symptoms.

Ask which examination findings suggest nerve-root irritation, whether your symptoms match the level shown on any scan, and what activities you can continue safely. Clarify how weakness will be monitored, when imaging would change management, and which medicine options fit your health history.
