Spinal stenosis: when the spine narrows around the nerves.
Stenosis means narrowing. In the spine it is the gradual crowding of the canal that carries the spinal cord and nerve roots, usually from arthritis and thickened ligaments that come with age. Many people live with it for years; some reach a point where a decompression gives their walking back.
Symptoms
Lumbar stenosis has a recognizable pattern: aching, heaviness, cramping, or numbness in the buttocks and legs that comes on with standing and walking and eases within minutes of sitting or leaning forward — the reason people with stenosis often find a shopping cart makes walking easier. Cervical stenosis, in the neck, is different and more serious when it compresses the spinal cord itself: clumsy hands, trouble with buttons or handwriting, unsteady walking, and sometimes bladder urgency.
Causes
Most stenosis is degenerative — the joints at the back of the spine enlarge with arthritis, the ligaments thicken, and discs flatten and bulge, all of which take up room in the canal. A vertebra that has slipped forward (spondylolisthesis) narrows it further. A smaller number of people are born with a narrow canal and develop symptoms earlier.
Diagnosis
The history often makes the diagnosis before any test. MRI confirms it and shows how tight the narrowing is and at which levels; CT is used when bone detail matters or MRI is not possible. Standing X-rays check for a slip or instability, which changes the surgical plan if surgery is ever needed.
Living with stenosis without surgery
Stenosis rarely becomes dangerous on its own, so the decision is about quality of life. Physical therapy focused on flexion-based exercise and core strength, activity pacing, weight management, and anti-inflammatory medication help many people manage for years. Epidural steroid injections can provide months of relief and are a reasonable step before considering surgery.
When surgery makes sense
Surgery is considered when walking distance has shrunk to the point that it limits daily life, when leg symptoms no longer respond to non-surgical care, or when nerve function is affected. For cervical stenosis pressing on the spinal cord, surgery is recommended earlier, because cord compression can cause damage that does not fully recover. The core operation is a decompression (laminectomy) that removes the bone and ligament crowding the nerves; when a slip or instability is present, it is combined with a fusion. Dr. Mushlin uses minimally invasive approaches — working between the muscles rather than through them — whenever they can achieve the same result safely.
Where to be seen
Dr. Mushlin sees patients at the Stony Brook Spine Institute offices in Riverhead, Lake Grove, and Commack, across Suffolk County. It helps to note before the visit how far you can walk before the legs give out, and what eases it.

Will spinal stenosis get worse?
Degenerative stenosis tends to progress slowly over years, but symptoms often fluctuate rather than steadily decline. Many people stabilize with therapy and activity changes. Cervical stenosis that affects the spinal cord is the exception and should be evaluated promptly.
Is walking bad for spinal stenosis?
No — staying active is protective. Walking to tolerance, cycling, and pool exercise keep the legs and heart strong. Leaning slightly forward, as on a bike or a walker, usually opens the canal enough to go further.
Can stenosis be cured?
The narrowing itself does not reverse without surgery, but the symptoms can be managed for a long time. A decompression physically removes the crowding and, in appropriately selected patients, restores walking distance reliably.
