Psoriasis is a chronic autoimmune skin disorder where skin cell re-growth is overactive. It causes red, itchy skin which becomes flaky and scaly. It can also lead to joint inflammation, or psoriatic arthritis, which 30% of people with psoriasis will develop. While psoriasis primarily affects the skin, it is also associated with different conditions, diseases and cancers completely unrelated to skin. Psoriasis has no cure, and is constantly recurring. There are a number of treatment medications, and most people will find topical corticosteroid creams and ointments sufficient for managing symptoms of plaque psoriasis. If needed, there are also oral forms of medication, or shots to aid immune system function. Find the best-priced psoriasis treatment here on Canada Drug Pharmacy.
