Nerve pain, also known as neuropathic pain, is a type of pain that is caused by injury or dysfunction to the nerves themselves. The term “neuropathy” refers to any disease or dysfunction affecting nerves in the body, which can lead to nerve pain. Radiculopathy is a specific type of neuropathy that occurs when a spinal nerve root is compressed, irritated, or inflamed, causing pain, numbness, or weakness in the area of the body supplied by that nerve.
