A psoriasis diagnosis is about more than skin, it's an immune system running too hot, and often comes with joint risk too. This is the calm, plain-English companion for what comes next. It explains the autoimmune mechanism behind psoriasis, the different types (plaque, guttate, and others), the link to psoriatic arthritis and why joint symptoms shouldn't be ignored, and the treatment categories from topicals to biologics. It covers common triggers and the infection risks worth knowing about. No jargon. No fear. No filler. Just what you actually need, in the order you need it, with clear tables, checklists, and the exact questions to bring to your next appointment.
