Psoriasis is a skin condition that is thought to stem from an improper or altered response of the immune system. Dry, scaly lesions may appear on the arms, legs, trunk, face or genital regions of the body. Triggers such as injuries to the skin, allergies, sunburn or infection may cause psoriasis to develop or worsen. People of any age may develop the disease but is most commonly diagnosed between the ages of 15 and 35.
Skin Symptoms
Scales that are silver, pink or red in color accumulate on the surface of the skin. The lesions may become hardened or thick and may itch or feel extremely dry. Pus-filled sores may appear on the skin in addition to or instead of scales.
Joint Pain
Joint pain may accompany skin symptoms in some people who have psoriasis. This symptom is referred to as psoriatic arthritis.
Topical Treatments
Psoriasis may be treated with a range of topical creams and ointments designed to soften and remove scales from the skin. Topical medications may contain steroids and are available in both over-the-counter and prescription strengths.
Light Therapy
The National Psoriasis Foundation explains that light therapy may help alleviate symptoms of moderate psoriasis in some people. Light therapy, also called phototherapy, involves exposing the affected area to ultraviolet rays.
Oral Medications
People who do not respond to topical treatments may choose to take oral medications to ease the symptoms of psoriasis. Methotrexate and Cyclosporine are two systemic medications prescribed for moderate or severe symptom, including psoriatic arthritis.
