The majority of the cases of referred itch studied by experimenters occur in healthy individuals. Furthermore, referred itch itself does not confer any adverse effects on the health of those experiencing it. With the exception of the annoyance of feeling multiple itches and a potentially minuscule feeling of pain, it is an innocuous condition.
The exact mechanism of the condition is unknown. Some studies have suggested the itching occurs in response to increased fibrinolytic activity in the skin, [5] [6] inappropriate activation of the sympathetic nervous system, [7] increased activity of acetylcholinesterase, [8] [9] or an increase in mast cell degranulation that releases histamine and other chemicals into the body.
Itch is readily abolished in skin areas treated with nociceptor excitotoxin capsaicin but remains unchanged in skin areas rendered touch insensitive by pretreatment with anti-inflammatory saponins. Although experimentally induced itch can still be perceived under a complete A-fiber conduction block , it is significantly diminished.
What it looks like: Psoriasis, another inflammatory condition that dermatologists see frequently, is known to causes scaly, itchy areas of thickened skin called plaques that can look like rashes.
The hives associated with aquagenic urticaria are typically small (approximately 1–3 mm), red- or skin-colored welts (called wheals) with clearly defined edges. It most commonly develops on the neck, upper trunk and arms, although it can occur anywhere on the body. Once the water source is removed, the rash generally fades within 30 to 60 ...

The condition manifests as an allergic-like reaction, causing a warm red wheal to appear on the skin. As it is often the result of scratches, involving contact with other materials, it can be confused with an allergic ...
