What is Mononeuropathy
Mononeuropathy is damage to a single nerve or nerve group, which results in loss of movement or sensation. Mononeuropathy is most often caused by injury, although systemic (body wide) disorders may cause isolated nerve damage. For example, Mononeutitis multiplex. Prolonged pressure on the nerve due to swelling or injury can result in Mononeuropathy. The covering of the nerve ( Myelin Sheath) or part of the nerve cell (the axon) is destroyed. This damage slows or prevents signaling through the nerves.
