6 Signs of Spinal Stenosis

Article feature on Spine-Health

Does your back, arm, or leg pain seem to come and go, depending on what you’re doing at the moment? This sign may indicate spinal stenosis.

Spinal stenosis happens when the bony openings for your spinal nerves (foramen) and/or the spinal cord (central canal) become narrow. This narrowing may compress your spinal cord and/or spinal nerves and can develop at various points along your spine. Spinal stenosis is a condition that’s more likely to occur in people over 60 years of age and tends to worsen as the years add up.

Here are 6 typical signs and symptoms to watch out for if you suspect your pain is from spinal stenosis. Depending on the type and location of the stenosis, one or more symptoms may be experienced:

1. Neurogenic claudication

When the nerves in your lower back get compressed, you may experience neurogenic claudication in your legs. Neurogenic claudication usually has the following characteristics:

  • Constant pain and/or numbness in your legs while standing
  • Increased pain and/or numbness in your legs while walking variable distances and/or while bending the spine backward
  • Difficulty in performing upright exercises or activities
  • Improvement or resolution of pain and/or numbness with rest

Neurogenic claudication pain is typically relieved when you bend your spine forward (such as while leaning on a shopping cart/walker, squatting, or sitting and leaning forward).

Your doctor will likely need to differentiate this pain from vascular claudication, which can mimic neurogenic claudication.

2. Sciatica

Compression of the nerve roots in your lower back may lead to lumbar radiculopathy or sciatica (depending on the nerve roots affected). Sciatica is experienced as nerve pain and weakness typically felt in one leg at a time.

Depending on the nerve root(s) affected, pain may occur in your lower back, buttock, thigh, calf, leg, and/or foot. A pins-and-needles sensation, tingling, weakness, and/or numbness may also occur in the areas affected by pain.

3. Foot drop

Compression of the L4 and L5 nerve roots in the lower spine may cause motor weakness in your foot, resulting in foot drop. This condition typically causes a feeling of weakness while attempting to lift the foot and/or toes upward. As a result, the individual may involuntarily drag their foot or tend to trip while attempting to walk.

The compression of the S1 nerve root may cause weakness while walking on tip-toes.

4. Gait problems

Spinal stenosis can affect walking in different ways depending on its location within the spine, for example:

  • Lumbar spinal stenosis (in the lower back) may cause gait problems due to foot drop. The condition may also cause weakness in thigh and leg muscles, such as the quadriceps and the calves.
  • Cervical spinal stenosis (in the neck) with spinal cord compression may cause difficulty in maintaining balance while walking, especially in the dark. However, cervical spine stenosis with a pinched nerve does not cause gait imbalance.

Changes in gait may be too subtle to notice at first. Over time, the condition may present with progressively increasing falls.

5. Radiating arm pain

Cervical spinal stenosis may cause mild to moderate burning or shock-like pain in the neck, shoulder, and/or arms. Abnormal sensations, such as tingling, crawling, and/or numbness may be felt in both hands. The arms and hands may feel weak.

6. Loss of fine motor skills

Spinal stenosis in the cervical spine may cause difficulty in doing tasks that involve fine motor skills of the hand, such as buttoning a shirt. In the advanced stages, there may be difficulty with writing, eventually making holding a pen impossible.

If these symptoms sound familiar, check with your doctor, since spinal stenosis may get worse without treatment.

Red-flag signs and symptoms of spinal stenosis

Rarely, severe spinal stenosis may cause red-flag symptoms, such as bowel and/or bladder incontinence, numbness in the inner thighs and genital area, and/or severe weakness in both legs.

These symptoms indicate a serious medical condition, such as cauda equina syndrome, which must be treated urgently to prevent permanent loss of function in the legs.

An accurate diagnosis by a medical professional is necessary to determine the underlying cause of spinal stenosis. Depending on the cause and severity, your doctor may suggest nonsurgical treatments, such as physical therapy, pain-relieving medications, and/or activity modification. Sometimes, minimally invasive procedures, such as epidural steroid injections may be advised. Surgery is rarely advocated as the first-line treatment unless there are severe symptoms or neurologic deficits.
