Neuropathy refers to a range of conditions that involve damage to the nerves, which can lead to symptoms such as pain, weakness, and numbness. It can affect various parts of the body and is often caused by underlying conditions like diabetes, autoimmune diseases, or infections. The most common type, peripheral neuropathy, typically affects the limbs and can significantly impact daily activities. Treatment options vary depending on the cause and may include medications, physical therapy, and lifestyle changes to manage symptoms and improve quality of life.
