Does anyone have any "home-based" solutions for severely dry, sensitive and itchy skin?

I suffer from severely dry and itchy skin, that often gets quite sore (like pins are in it). On occasion I get eczema too. In my last consult with my dermatologist, I was prescribed a low-dose cortical steroid cream for whole body application and a higher dose one for areas affected by eczema. I was also prescribed SBR Barrier Repair Cream for whole body application. I have run out of the aforesaid, and will have to wait till at least Monday to get another script. Does anyone have a home-remedy I could use in the interim?
