I have been getting dry patches that peel and turn red and puffy behind my neck for about 3 years now and found out last year that it is psoriasis. I  went to the dermatologist and he gave me a fungal cream and lotion for it. The lotion he gave me irritated it more. And now for the last two days I noticed that the psoriasis spreader mildly on my nose! Does anyone know of any home remedies?!
