Neuropathy is a condition that affects the nerves in the body. Each nerve has a special covering and when that covering is damaged, the nerve doesn't function normally. A "tingling" sensation or a feeling of "pins and needles" may be a warning sign to the patient that their nerves are functioning abnormally. When the condition of neuropathy worsens, the patient may lose complete feeling in different parts of their body. Most commonly, neuropathy tends to affect the hands and feet. When the hands and feet become neuropathic, it is very difficult for one to carry out their activities of daily living.
