What is neuropathic pain?

Neuropathic pain is defined as pain that arises from damage to the peripheral or central nervous system. This type of pain is often a result of conditions such as diabetes, multiple sclerosis, or injury to the nerves, which can disrupt the normal signaling pathways of pain to the brain. Unlike nociceptive pain, which is typically a protective response to tissue injury or inflammation, neuropathic pain arises from abnormal processing of sensory input due to the dysfunction of the nervous system itself.

It may present as a burning, tingling, or shock-like sensation, and can be chronic in nature. Understanding the mechanisms behind neuropathic pain is crucial for effective treatment, as it often requires different management strategies compared to pain arising from physical injury or inflammation.
