As skin rashes are common, doctors have to rule out other causes, such as allergic reactions to food or medication, viruses, or eczema, before they can make a diagnosis of psoriasis. A psoriasis diagnosis requires careful visual inspection and sometimes even a skin biopsy. If you are concerned you may have psoriasis you should visit your GP or ask for a referral to a dermatologist.
Hammerberg C Regardless of where psoriasis forms, the cause is the same. Psoriasis develops when a person’s immune system has faulty signals that tell skin cells to grow too quickly. New skin cells form in days rather than weeks. The body does not shed these excess skin cells. The skin cells pile up on the surface of the skin, causing patches of psoriasis to appear.

Discounts Erythrodermic psoriasis is a severe and very rare type of psoriasis. This form often covers large sections of the body at once. The skin almost appears sunburned. Scales that develop often slough off in large sections or sheets. It’s not uncommon for a person with this type of psoriasis to run a fever or become very ill. This type can be life-threatening, so individuals should see a doctor immediately.
Ultraviolet light can help slow the growth of skin cells triggered by psoriasis. This type of therapy often requires consistent and frequent sessions.
