The peripheral nervous system connects the nerves from the brain and spinal cord to the rest of the body. The signals of physical sensations are delivered to the brain by these nerves. Malfunction of these nerves causes peripheral neuropathy affecting the normal functioning. False signals of pain may be send to the brain when there is nothing causing pain while they might send a signal when some is actually harming you. It can occur due injury, systemic illness, infection or may be inherited.
There are several different kinds of peripheral neuropathies.
Mononeuropathy occurs when a single peripheral nerve is damaged. It may be caused by a injury or trauma from an accident. Keep sitting or lying at the same place for long hours can trigger a mononeuropathy. The common type of mononeuropathy is carpal tunnel syndrome which occurs when the nerves that pass through the wrist are compressed. The damage to the nerve results in numbness, tingling, unusual sensations and pain in the first three fingers of the hand.
When multiple peripheral nerves throughout the body malfunction at same time, the condition is called polyneuropathy. The causes that lead to polyneuropathy include exposure to certain toxins, poor nutrition, and complications from diseases like cancer and kidney failure.
