I had this itchy rash since Jan. 2013 that would get itchy then bumpy with clear liquids that come out. It spread throughout the year and would come and go. Occasionally it will split open and bleed. I've heard eczema or poison ivy, but no cortisone, oat, or antibacterial will cure. Typically, it comes and goes but now I have it on my knuckles and cracks and bumps on both hands. WHAT IS THIS??
