Visual symptoms of psoriasis on the legs include red, scaly patches and cracked skin, according to Mayo Clinic. Other symptoms of psoriasis on the legs are soreness, burning, itching, swelling and stiff joints.
The three main types of psoriasis treatments are topical treatments, systemic medication and light therapy, explains Mayo Clinic. People often use topical creams and ointments to treat mild-to-moderate forms of psoriasis, and the treatments include topical corticosteroids, vitamin D analogues, salicylic acid and calcineurin inhibitors. Systemic medication is also an option, and patients take these medicines orally or through an injection. These medications include retinoids, cyclosporine and methotrexate.
Light therapy is another way that people treat psoriasis, and natural sunlight is the preferred method of treatment, claims Mayo Clinic. Natural sunlight works to activate the T cells in the skin, which slows the turnover of the skin and reduces redness. UVB phototherapy is another option for patients, and it often helps to improve mild-to-moderate psoriasis. The Goeckerman treatment also uses UVB therapy, but with this treatment, coal tar is an added ingredient, which makes the skin more receptive to the light.
Most of the treatments for psoriasis have few side effects, states Mayo Clinic. If there are side effects, a patient should talk to a doctor about trying other treatments.
