Psoriasis is an autoimmune skin disease. It is controllable disease. I can understand your anxiety for your  disease. But,you have to keep patience. Stress might exacerbate the disease.You may get relief slowly. You consult eminent dermatologist for firm diagnosis and perfect treatment. I would like to suggest acitretin 25 mg daily along with methotraxate 15 mg weekly in three devided doses of 5 mg 12 hourly. Blood tests may be done at regular intervals.Steroid with salicylic acid oint may be applied twice a day on psoriatic lesions. After clearance of lesions, there may be hypopigmention. You may apply mild steroid cream like mometasone cream. Soap bath should be avoided. You may use dettol liq for bath. Pour 5 drops in a bucket filled with water.All precautions may be taken to avoid dryness of skin. Moisturiser cream should be considered.After few months, he may be alright. But, maintenance therapy may be continued.Thanks.Dr. Ilyas Patel MD </s>
