Psoriasis is chronic (long lasting) condition which can be controlled but not cured.
It presents as multiple itchy red lesions with silvery white flakes. This formation of skin flakes is because of a rapid growth of skin cells. Often nails are also found to be affected.
Psoriasis is commonly seen on lower back, elbow, knees, palms, soles, scalp etc. It can be localised or generalised.
In about 25% of the cases it is accompanied by psoriatic arthritis.
Aggravating factors include:
Sudden weather changes
Mild trauma or injury can trigger new patches
