Neuropathic Itch Defined
- Neuropathic itch is a common type of itch without a primary rash, caused by nervous system dysfunction, not inflammation.
- It often affects localized areas like the scalp, back, or arms, and can range from mild to intense.
Sudden Itch
- Dr. Kwatra's wife experienced sudden, debilitating itch on her back, a common symptom of neuropathic itch.
- Studies suggest that strengthening muscles and exercise can sometimes relieve this type of itch.
Itch and Pain Pathways
- Itch and pain signals travel similar pathways from the skin to the brain, sometimes overlapping.
- Issues anywhere along this pathway can cause neuropathic itch, including strokes or brain overactivity.
