Psoriasis is a chronic skin condition that can come and go over time. Psoriasis causes red irritated flaky skin. It is not contagious. Although the exact cause and cure for psoriasis is unknown, there are many products and prescriptions that can help relieve your symptoms.
Psoriasis causes areas of irritated red thick skin. The affected areas may have flaky silver-white colored scales. In males, psoriasis can cause genital sores. Almost a third of people with psoriasis develop aching joints (psoriatic arthritis) and about 10% experience changes in nail appearance or separation of the nail from its base.
You should seek urgent care if you have a very severe outbreak of psoriasis that covers most of your body.
Psoriasis develops most frequently between the ages of 15 and 35, although it may occur at any age. People with weakened immune systems, such as those with HIV/AIDS, autoimmune disorders, cancer, or who are receiving chemotherapy may have an increased risk of psoriasis. Psoriasis may be triggered by dry air, dry skin, certain medications (beta-blockers and lithium), stress, infection, alcohol, too little sunlight, and sunburn.
