Spinal Stenosis

Written & medically reviewed by Dr. Sanjay Anbu, MBBS · Last reviewed 27 September 2026

Spinal stenosis is a narrowing of the spinal canal that puts pressure on the spinal cord or nerves, usually in the lower back or neck. It commonly causes leg pain that eases when you sit or bend forward.

Frequently asked questions

Why is walking harder than standing still?

Walking upright narrows the canal further and pinches the nerves, causing leg pain. Bending forward, such as leaning on a trolley, opens the space and often relieves symptoms.

Will I need surgery?

Many people manage well with exercise, pain relief and activity changes. Surgery is considered when symptoms are severe, worsening or limiting walking despite these measures.
