Neuropathic rest pain is a condition characterized by persistent pain, often occurring during periods of rest. This discomfort arises from nerve damage, leading to abnormal signaling between the nerves and the brain. In this comprehensive guide, we’ll explore the types, causes, symptoms, diagnostic tests, and various treatments, including drugs and surgery.
Types:
- Peripheral Neuropathy: Peripheral neuropathy is a common type of neuropathic rest pain, affecting the nerves outside the brain and spinal cord.
- Diabetic Neuropathy: This type is specifically linked to diabetes and is a result of prolonged high blood sugar levels damaging nerves.
- Postherpetic Neuralgia: Caused by the varicella-zoster virus, postherpetic neuralgia occurs after a bout of shingles.
- Entrapment Neuropathy: Pressure on nerves, often due to surrounding structures like ligaments or bones, can lead to entrapment neuropathy.
Causes
- Diabetes: Persistent high blood sugar levels can damage nerves, leading to neuropathic rest pain.
