The spine is designed to protect the spinal cord. However, the spaces between the bones can narrow due to injury or aging, leading to a condition called spinal stenosis. It can induce pressure on the nerves that spread out from your spine, causing different symptoms that get worse with time. Worry no more as an interventional pain specialist in Houston provides treatments that relieve spinal stenosis symptoms.

How is spinal stenosis diagnosed?

Your doctor reviews your medical history, asks about the symptoms you are experiencing, and conducts a physical exam. While doing a physical exam, your doctor feels your spine by pressing it on different areas to see if you feel pain. Your doctor will ask you to bend in various directions to check if different spine positions bring pain or other symptoms. He also checks your balance, watches how you walk and move, and checks your leg and arm strength.

Your provider will do imaging tests to examine the spine and know the exact location, extent, and type of the problem. Some of the imaging tests include:

X-rays: it uses a small amount of radiation and shows changes in the bone structure, as the development of bone spurs and disk height narrows the spine’s spaces.

MRI: MRI uses radio waves and magnets to create images of the spine. MRI images give detailed images of the discs, spinal cord, nerves, and presence of tumors.

CT or CT myelogram: this scan is a combination of imaging that creates cross-sectional images of the vertebrae.

What causes spinal stenosis?

1.     Arthritic spurs or bone overgrowth

Osteoarthritis is a condition that breaks down the cartilage in the joints, the spine included. Cartilage is the cover that protects the joints. When the cartilage wears, the bones start to rub against one another. The body responds by growing another bone. An overgrowth of the bone or bone spurs commonly occurs. Bone spurs extend to the spinal canal, pinching nerves and narrowing the space in the spine.

2.     Bulging or herniated disk

Between every vertebra is a round, flat cushioning pad that acts as a shock absorber on the spine. Age-related flattening and drying out of vertebral disks and cracking on the outer part of the disk cause the disks’ gel-like center to tear or break the outer layer. The bulging disk presses on the nerves near the disk.

Symptoms of spinal stenosis

You may or may not have symptoms when spinal stenosis develops. Narrowing of the spinal canal is always a slow process and gets worse with time. Spinal stenosis can happen anywhere along the spine. Some lower back spinal stenosis symptoms include back pain, tingling or numbness in a leg or foot, weakness in the leg or foot, and cramping or pain in one or both legs. Other symptoms of spinal stenosis in the neck include neck pain, problems with walking and balance, and tingling in a hand or arm.

Many people with spinal stenosis live active lives, but they must adjust their routine exercise or daily activities to assist in managing the symptoms of spinal stenosis. Your healthcare provider can prescribe medications, surgery treatments, or physical therapy to relieve pain and other symptoms.
