Rash spreading on wrist

I burned the side of my wrist when it touched up against the inside of the stove. No big deal, I have been burned before. then a rash started to appear and has continued to spread. It is red and cracking with small bumps appearing along the outer edge. They appear sporadic and then multiply the rash is also "weeping" a liquid that is yellowish in color. I have tried triple antibiotic (neosporin) I keep it wrapped in gauze and change the gauze a couple times a day, but I can't seem to stop the spread or get this thing to heal up. What can I do to cure this??
Thanks
