Stenosis is a condition that can develop as a person ages, particularly
in those over 50. It is characterized by a narrowing of the spinal
canal, which places pressure on the spinal cord and nerves, because
there is not enough room for them. It resembles placing a ring on
your finger. If the finger becomes injured or inflamed, the ring
constricts and causes pain. The pain caused by stenosis is typically
focused in the low back area and can shoot down the legs and flare
up after walking or exercising.
Narrowing of the spinal canal may be genetic. However, the primary contributing factor to the development of stenosis is degenerative disc disease. As the spine undergoes changes in stability, density and size, this can result in less space for and more pressure on the spinal structures.
When one area of the spine is injured, it is more likely
that spinal health in other areas will fail. Conditions that may encourage
the development of stenosis include scoliosis, osteoarthritis, rheumatoid
arthritis, spinal tumors and trauma.
Symptoms of stenosis include a deep aching in the low back, buttocks
and thigh, and intense numbness or pain in the legs and sometimes
the shoulders. Symptoms can be brought on by walking and exercise.
If you have stenosis, you may notice that pain is sometimes relieved
by sitting or by a position in which the spine is flexed forward
and bending over. Consequently, people with stenosis may walk with
a hunched over posture and find that their pain worsens when bending
backward. Severe cases of stenosis will display more serious symptoms
such as loss of bowel and bladder function and loss of feeling in

In many cases, changing posture and using spinal injections can control the symptoms for a long period of time. Stenosis can be treated nonsurgically, but some cases require surgery in order to create more space around the nerves.
Pain can be relieved by flexing forward and bending over. Taking anti-inflammatories may be beneficial, especially ibuprofen products like Advil or Nuprin. Acetominophen (Tylenol) can be taken for pain, if you are allergic to ibuprofen. A physical therapy program can be followed that incorporates stretches and movements that extend the spine. Injections may be used to reduce inflammation and control pain symptoms. Try our home remedy exercises provided. Stop if they cause an increase in pain or symptoms.
The most common surgery to treat stenosis is called a laminectomy, which helps create more space for the surrounding spinal nerves. Now at SpineNevada there is a new non-fusion treatment option for spinal stenosis.
Dr. James Lynch at SpineNevada Minimally Invasive Spine Institute recently became the first in Northern Nevada to use the coflex® Dynamic Stabilization device for the treatment of Spinal Stenosis. This non-fusion treatment option can help spinal stenosis patients return to activity faster than with traditional surgical options.

Although degenerating discs are the most common cause of spinal stenosis,
spinal tumors, injury, bone disease and other conditions can lead to
stenosis as well. For example, primary stenosis results from diseases
that are present at birth, while acquired stenosis is typically the
result of degeneration in the spine.
If pain interferes with your daily activities, you should consult a spine specialist to treat your stenosis. Leg pain that worsens is especially an indicator of spinal stenosis. This type of pain is not a normal part of the aging process.
Treatment for spinal stenosis aims at minimizing the effects and symptoms of the stenosis but does not stop the progression of degenerative changes. Adopting a healthy lifestyle that includes exercise can help prevent disc degeneration. Click here to learn more about degenerative disc disease.
If your pain is severe enough or if walking has become difficult, your
physician may consider surgery as an option for you. However, nonsurgical,
conservative treatments are usually effective at treating spinal stenosis.
