Cervical spinal stenosis is the narrowing of the spinal canal in the cervical region. This narrowing is problematic because it compresses the spinal cord and the spinal nerves that exit the spinal column. This results in significant symptoms, particularly in the upper extremities. However, MayoClinic.com states that cervical spinal stenosis rarely causes neck pain. A patient should be aware of the symptoms of cervical spinal stenosis and know what to do if they are experienced.
Numbness
Numbness in the arms or hands may be a symptom of cervical spinal stenosis, states MayoClinic.com. This occurs because the upper spinal cord is compressed by osteoarthritis, or other bone conditions. In addition, the spinal nerves that exit the spinal column and travel to the arms and hands are compressed. This results in numbness along specific areas of the arm or hands, depending on which nerves are affected. A patient experiencing these symptoms should schedule an appointment with the doctor. The doctor will likely take X-rays or an MRI to assess the cause of numbness in the upper extremity.
Weakness
Medline Plus, of the National Institutes of Health, states that the upper body may become weak in severe cervical stenosis. This occurs because nerves that send signals to muscles are affected by cervical spinal stenosis. This results in a weak or disrupted signal that is sent to the muscles. A patient may experience difficulty lifting objects or grabbing objects. Weakness in the upper extremities requires proper diagnosis and treatment from a doctor. He may prescribe physical therapy to improve strength of the upper extremity.
Loss of Bowel or Bladder Control
According to MayoClinic.com, the loss of bowel or bladder control is a serious symptom associated with severe cervical canal stenosis. Nerves originate in the brain that control bowel and bladder functions. In order to reach the bowel and bladder, these nerves must travel from the brain, through the spinal cord and to the proper organs. With severe cervical spinal stenosis, these nerves can be compressed and cause the loss of control of bowel or bladder functions. This is a serious case of cervical stenosis and requires prompt medical treatment. The doctor will first rule out other causes of bowel or bladder dysfunction. Then, he will X-ray or MRI the neck and back to determine the severity of compression. Surgery may be recommended if the loss of bowel or bladder function is associated with cervical stenosis.
