Minimal Skin Involvement with Psoriatic Arthritis

@whicheveroneiam textbook pictures of psoriasis looks so painful and terrible. For years I've just thought the rashes were vitamin deficiency, allergic reactions, or "chapped" skin from the cold. It's weird too because mine presents a lot like RA because it's even on both sides in my hands and feet except for SI joint involvement on only one side. That's the only joint it's uneven on. Then I got a tiny little elbow rash, red and flakey, so I showed my doctor and sure enough... it's so weird.
