What clinical symptoms does spinal stenosis result in?

• A. Numbness in the hands
• B. Lower back pain only
• C. Compression of the nerves, arteries, capillaries and veins
• D. Swelling of the legs

Answer: (C)

Spinal stenosis narrows the spinal canal and directly compresses neural structures. When the nerves or spinal cord are pressed, patients typically develop leg symptoms such as pain, numbness or tingling, weakness, and the hallmark neurogenic claudication—leg symptoms that worsen with walking or standing andoften improve with bending forward or sitting. The narrowing can also encroach on nearby blood vessels, and while the primary clinical issue is nerve compression, vascular compromise can contribute to ischemic changes in neural tissue. That’s why the option describing compression of nerves, arteries, capillaries and veins best reflects what happens in spinal stenosis. Numbness in the hands would point to a cervical issue, not spinal stenosis of the lumbar region. A claim of “lower back pain only” misses the neurological leg symptoms that characterize the condition, and swelling of the legs is not a typical or specific feature of spinal stenosis.
