Lumbar spinal stenosis (LSS) refers to the narrowing of the spinal canal in the lumbar region, leading to compression of the nerve roots in this area.

Symptoms typically worsen with activities such as standing and, especially, walking, but tend to ease with rest.

Causes of lumbar spinal stenosis include degenerative changes in bone structures due to aging, thickening of ligaments within the canal, herniation, joint osteoarthritis, and tumors in this region.

The following symptoms are particularly observed during walking a certain distance:

• Back pain: Pain or discomfort in the lower back.
• Leg pain: Pain radiating to the buttocks, thigh, knee, or foot.
• Numbness and tingling:Sensations of numbness, tingling, or burning in the legs, feet, or groin.
• Difficulty walking: As lumbar spinal stenosis progresses, difficulty walking may arise along with weakness and imbalance in the legs. This is known as "claudication."
• Bladder or bowel issues: Progression of lumbar spinal stenosis can lead to problems with bladder or bowel control due to compression on the spinal cord.

These symptoms can vary depending on the degree of stenosis and the extent of compression on the spinal cord and nerve roots. Symptoms typically worsen during stressful conditions on the spine, such as activity or prolonged walking, and alleviate with rest. The severity of complaints may differ from person to person.

The treatment of lumbar spinal stenosis varies based on the severity of symptoms and the patient's condition. Initial treatment options include physical therapy, exercises, and epidural corticosteroid injections. In advanced cases, surgical intervention may be necessary.
