October 28, Overuse injuries to peripheral nerves in the upper extremities are a common but an often ignored problem, according to David Megee, MD, a plastic, reconstructive and hand surgery specialist with UC Health. The peripheral nervous system is a vast network of specialized nerves responsible for transmitting messages sent from the central nervous system brain and spinal cord to the rest of the body. This includes sensory information that allows us to feel the difference between, for example, hot and cold. Megee says most peripheral nerve injuries can be corrected through behavior modification and improved body mechanics: avoiding repetitive tasks, applying principles of ergonomics and avoiding devices that apply physical pressure to sensitive areas. When this does not give the patient relief, surgery may help restore function.
