A pinched nerve is damage or injury to a nerve or set of nerves from compression or constricting. Motor nerves, those that carry information from the brain to the body, and sensory nerves, those that send information from the body to the brain for processing information about pain, touch, taste temperature and other sensations, can be affected by a pinched nerve. The condition is more prevalent in women than men. It also affects people with poor posture, rheumatoid arthritis, bone spurs, pregnant women, those who are obese and those with repetitive strain injuries.
