Psoriasis doesn't have any set way of progressing. Some people may only have occasional and minor symptoms for their entire lives; others may have to cope with severe symptoms on a regular basis.
In most people, the symptoms come and go. Flare-ups might be brought on by some conditions like dry weather or stress.
Untreated, extremely severe psoriasis can be dangerous. Although it happens very rarely, if lesions cover enough of the body, the immune system can become overwhelmed. Be sure to see your doctor immediately if your psoriasis spreads to cover large parts of your body or if you show signs of infection, such as fever.
Coping with psoriasis can be exhausting and frustrating. It's important to try to stay emotionally and physically healthy during treatment.
