Essentials of Clinical Reasoning 2

"A 25 year old woman who is fatigued, I always think pregnancy."
oh god. 50% of the M2 class is pregnant.

Eczema... Psioriasis

I aced the "Essentials of Clinical Reasoning" (ECR) exam on dermatology. I aced it. And yet... I still have no idea what's causing the skin around my nose and under my eyes to flake. I'm not sure if the white patch above my shin is an autoimmune response or simply a response to irritation from all the wool socks I wear. I know that eczema runs in my family. But the one time I saw a dermatologist, he told me I had psioriasis alba. So no matter how much I try to clinically reason with myself, I still fall short of any conclusive self-diagnosis. Moral? Good grades are not congruent with applicable knowledge.
