A number of conditions may cause tissue to compress a nerve or nerves. Injury, poor posture, osteoarthritis, stress from repetitive job, hobby or sports activities, and obesity are common contributors to or causes of nerve pressure.
This pressure causes inflammation of the nerve and disrupts the nerve’s function. If a nerve is pinched for only a short time, there’s typically no permanent damage. Once the pressure is relieved, nerve function returns to normal. However, if the pressure continues, chronic pain and permanent nerve damage can occur.
