A few years ago, I scratched my hand while working on my car. The only thing else that the scratch came in contact with was some brake cleaner fluid. This scratch turned into a an itchy infection, which starts as just raised red spots, then secretes a yellowish fluid in tiny amounts which hardens on the sore. From there, the tiny sores gradually grow together to form one giant, dry, itchy, painful, and slightly yellowy-oozy sore which covers the entire back of my right hand. It also jumped to my left hand, although only ever was able to cover half the hand. Over-the-counter antibiotics don't seem to work (Neosporin, Bacitracin, store-brand triple antibiotic cream) at all except for providing relief from itching. I was prescribed a 0.1% Triamcinolone ointment by my doctor, and it worked. As long as I put the ointment on, the infection dies and eventually disappears entirely. However, no matter how long I use the ointment for, the infection always returns a week or two after stopping. I don't want to be putting a medicated cream on my hands for the rest of my life. Any suggestions as to either what this might be, or how I can get rid of it for good?
