"Psoriasis is a chronic, autoimmune disease that appears on the skin. It occurs when the immune system sends out faulty signals that speed up the growth cycle of skin cells. Psoriasis is not contagious.
Psoriasis is the most common autoimmune disease in the U.S. As many as 7.5 million Americans have psoriasis. Psoriasis has been linked to other serious health conditions, such as cardiovascular disease and depression. About 30 percent of people with psoriasis develop psoriatic arthritis.
There are five types of psoriasis. The most common form, plaque psoriasis, appears as raised, red patches covered with a silvery white buildup of dead skin cells. Psoriasis can occur on any part of the body and is associated with other serious health conditions, such as diabetes, heart disease and depression."

I was diagnosed with psoriasis in 2012, but believe I started to notice the undiagnosed symptoms as early as 2005. Some of my triggers are stress and non-serious injuries to the skin. At the most, I have only had 20% of my body covered at once. I have had psoriasis on my eyelids, my face, my legs and most often and most severely on my feet. I notice recurrences in the same places, as if my psoriasis has a memory. A few moments of stress can trigger a flare in me within the hour. I also notice that when psoriatic arthritis causes me pain, psoriasis will also flare in response. I see my dermatologist at least once a year for a check-up and, thankfully, have not had any skin emergencies since my diagnosis. I credit this to following the doctor's orders, eating well, taking good care of my skin every day and getting my medications on time.
