In The Past Ive Had Psoriasis On My Legs. After

in the past Ive had psoriasis on my legs. after a long time it healed. i had a itch behind my ear...flaking,..........and now a type of oozing? i keep finding a trail of wetness behind my ear .. goes to my ear lobe. my theory is I have some kind of a psoriasis flare up, itched it....musta became raw.....and wetness oozing from it?

I want it all gone of course. mostly the wetness oozing is most bothersome.

any advice?

I am a 54 yr male
