Why does my psoriasis itch, and how do I control the itching?
Itching that is associated with psoriasis arises when certain chemicals stimulate nerve fibers just below the outer layer of the skin. ‘Itch’ messages travel to the brain along the same pathways in the nervous system that carry pain messages. It is these itch messages that trigger the urge to scratch.
One of the simplest ways for people with psoriasis to control itching, is by keeping the skin well moisturized. Dry skin can induce and aggravate an itch. Many people also rely on some simple but inexpensive measures, such as pressing a wet towel against the itchy spot. Others find cold showers and cold packs offer relief. Other treatments for itching include antihistamines, steroids, capsaicin, topical anesthetics, topical immunomodulators, antidepressants and aspirin. Consult your doctor for your best options.
