Psoriasis is a chronic (long-lasting) condition that can be controlled but not cured.
It presents multiple itchy red lesions with silvery white flakes. This formation of skin flakes is because of the rapid growth of skin cells. Often, nails are also found to be affected.
Psoriasis is commonly seen on the lower back, elbows, knees, palms, soles, scalp, etc. It can be localized or generalized.
In about 25% of the cases, it is accompanied by psoriatic arthritis.
