Polyneuropathy may be defined as the simultaneous malfunctioning of the peripheral nerves of the brain. It usually begins in legs and then moves upward to arms. It causes weakness and often a numbing sensation. The pain becomes so excruciating that it may result in respiratory failure, affecting the muscles that control breathing. Some of the causes of polyneuropathy include kidney or liver failure, cancer, diabetes, autoimmune disorder or certain drugs and toxins.
HOW IS POLYNEUROPATHY DIAGNOSED?
Nerve conduction studies and electromyography are some tests that are conducted to diagnose the disease.
