What is a Pinched Nerve?
The term “pinched nerve” is used to describe the condition when a nerve is being compressed by the surrounding tissues
What are some of the symptoms of a pinched nerve?
Some signs and symptoms associated with pinched nerves include changes in sensation or numbness along the distribution of the nerve.
Sometimes a burning pain that may have an aching or sharp quality can be associated with a pinched nerve.
When a nerve is pinched and not functioning properly, you may get the feeling that your foot or hand has fallen asleep.
What causes a pinched nerve?
There are many causes of nerve compression. For instance, in the case of a herniated disc, the center of the disc is often protruding out into the spinal canal causing compression on a nerve or the spinal cord. In carpal tunnel syndrome, thickening of ligaments, inflammation of tendon sheaths, and/or arthritic changes can cause pressure over the median nerve. Sometimes, repetitive stress is from work, hobbies, or other activities can cause thickening of tissues and pressure on nerves. Obesity is also associated with increased incidence of nerve compression.
Sometimes inherent differences can lead to increase risk of certain problems. For instance, women tend to have smaller carpal tunnels so they are more prone to get carpal tunnel syndrome than men.
Women tend to also have increased risk of nerve compression during pregnancy because of water retention and weight gain during that time.
Inflammatory processes such as rheumatoid arthritis can cause changes in bones and joints as well as inflammatory changes in surrounding tissue that can compress nerves.
Having conditions like thyroid disease or diabetes can increase the likelihood of having nerve compression.
Sometimes occupational risk or activities can increase the risk of having a pensioner. Examples of this include jobs with highly repetitive movements such as assembly-line work.
