If you are one of the three percent of the population that gets psoriasis, the first psoriasis symptoms you may notice include:
Reddish patches of skin,
Scaly or flaky white coating on the skin,
Dry and cracked skin (the cracks may penetrate deep enough to bleed),
Thickened nails, sometimes pitted or with distinctive ridges,
Itching, burning or tender skin,
Stiff, swollen joints.
In young children, who are also susceptible to psoriasis, the problem may first appear as small, scaling areas on the skin. Psoriatic outbreaks can be very mild a patch of psoriatic skin on the knee that persists for several months and disappears but recur in about half of cases.
Each form of psoriasis, however, has its own, unique symptoms. That is, while plague psoriasis can appear anywhere, nail psoriasis as its name suggests attacks only fingernails and toenails. If this form of psoriasis becomes severe enough, sufferers may even find their nails crumbling, or peeling away from the nail bed entirely.
Scalp psoriasis appears as reddened, itchy patches, sometimes with silvery-white edges that extend beyond the hairline. If you scratch, you will notice flakes similar to dandruff, but this is not dandruff, and if ignored can cause hair loss.
Guttate psoriasis usually occurs in people under 30, and typically in response to a strep throat. Guttate psoriatic lesions can be identified by the fact that they are not as large, or as thick, as typical psoriatic plaques.
Inverse psoriasis is closely related with obesity, and appears in skin folds in the groin, under the breasts, and in the armpits. Doctors think inverse psoriasis may be triggered by a fungus.
Pustular psoriasis produces blisters, and can also cause fever, chills, severe itching, and diarrhea.
Last, but not least, is erythrodermic psoriasis covers the body with a reddish and peeling rash.
