Itchy Body

I'm wondering if its related to stress - attempting to quash internal conflict is causing my body to break out into eczema or at least, crawling all over with itching. Backs of knees, insides of elbows, the bruise on my upper right thigh has mutated from a black-pudding, pounded flesh deposit to a mass of eczema welts. Not particularly attractive, and unbelievably itchy. And other parts of me are tickling for itching too - the more I think about it the more I need to scratch my head, my stomach, my legs, under my right breast, behind my left ear, the back of my neck... It feels like little tiny bugs are crawling all over me. Driving me crazy and I feel like a filthy filthy individual. I want to have a shower with a huge handful of exfoliant and use exfoliant gloves too and go CRAZY itching my body.
