Dyshidrosis is a type of dermatitis, characterized by itchy vesicles of 1–2 mm in size, on the palms of the hands, sides of fingers, or bottoms of the feet. [8] Outbreaks usually conclude within three to four weeks, but often recur. [4] [8] Repeated attacks may result in fissures and skin thickening. [7] The cause of the condition is not ...
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.

High concentration topical capsaicin (8%, Qutenza) have been shown to be highly effective in treating neuropathic itch in some patients [12] [13] (including notalgia paresthetica) as well as in a recent proof-of-concept study. [14] Most recently intradermal injections of botulinum toxin type A (Botox) have been tried with some success. Even ...
Pain and itch have very different behavioral response patterns. Pain elicits a withdrawal reflex, which leads to retraction and therefore a reaction trying to protect an endangered part of the body. Itch in contrast creates a scratch reflex, which draws one to the affected skin site. Itch generates stimulus of a foreign object underneath or ...
