I don't understand why suddenly I am having issues with psoriasis everywhere. This is totally new. Before it was only on my scalp now my back, legs and arms are driving me crazy.

Actually I am assuming it is psoriasis because I don't know what it looks like. It is like very dry skin and itches like crazy

Hi Robyn,
It’s best to get in touch with your doctor when you have weird new symptoms. If you don’t typically get P anywhere but your scalp and you now have itchy skin on many parts if your body I would get in to your doctor ASAP. It may or may not be P but you certainly need to get your skin examined. Good luck!
