Apart from the pill have you changed anything else? Your soap or shampoo, laundry detergent? Any major changes to your diet?

I have a male friend who has in the last two months developed terrible psoriasis. He has never had it before and it is quite severe on his face, scalp, hands and (his wife tells me!!) his genitals (both the frank and the beans!). He is seeing a psoriasis clinic who have suggested it is caused by recent stress. Have you been particularly stressed lately?
