I have had Psoriasis on my scalp for coming up 2 years now, and nothing my doc has prescribed has worked. Lately, I have had a few (initially) small very dry patches come upon my face. They have got bigger slowly, and my doc has said that it's Impetigo, and he's given me some cream for it (Fucidin). My problem now is that I have some really itchy patches coming up in my hairline, - are they the Psoriasis creeping there, or could it be the Impetigo? IfI scratch a piece off, it looks like bits of old wallpaper paste, - - daft I know, but tthat's the only way I can describe it ☺ Can anyone help me with this?
