question: A part of my skin is really itching since the last 2 months. I bought a product named Psoriasis to try to cure it but it didn't change anything. Now i'm getting scared cause the itching part just get's bigger and bigger (about 7inches by 4 inches). I'm not sure it is psoriasis but i saw pictures of that and it seemed the same. Hope you will help me as fast as possible . :) thanks.
