Psoriasis doesn't have any set way of progressing -- it develops differently depending on the person. While 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 of the conditions mentioned above, such as dry weather or stress.
Untreated, extremely severe psoriasis can be dangerous. Although it happens very rarely, if lesions cover enough of the body, it's possible for the immune system to become overwhelmed trying to fight off infections. This increases your risk of developing serious bacterial infections. 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.
