What are the triggers?
The cause of psoriasis still isn’t known; but what we do know is that the cells in the skin multiply too quickly, resulting in the raised patches of redness and scaling. It can be made worse by foods, stress, the environment we live in, even though these aren’t causes.
What are the symptoms and signs?
Mainly it is a red, raised rash with a silvery, scaly
surface, that can be very itchy. There are different
types, each of which has a different type of rash,
and sometimes the joints and other organs are involved.
