Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain itch and its causes and mechanisms, relay general self-care and when-to-seek-care guidance from health bodies, describe treatment approaches in general terms, and route personal medical questions to clinicians.

An unpleasant skin sensation that provokes the desire to scratch, known medically as pruritus, arising from skin conditions such as eczema and dermatitis, infestations and contact with irritants, from systemic causes such as liver, kidney and blood disorders, from nerve-related causes such as brachioradial pruritus, and from healing burns, and occurring in localised forms such as anal pruritus; itch is a common symptom assessed by cause and treated with skin care, medicines and management of the underlying condition.

What it is for: The symptom of itching.

It can be explain causes and mechanisms; relay self-care guidance; describe treatments generally; route personal questions.

Distinguishing features

Itch-scratch cycle

Localised or generalised

What it looks like

Not visible; a sensation, sometimes with scratch marks or rash.

How it is recognised

Sensation provoking scratching
