I applied Iodine on the back of my neck where I have a bump and it is now showing rash like symtomps with swelling,itching and redness. Swelling increased in the last2 days.I think this bump was very toxic with heavy metal accumulation. Iodine must have moved the metal around. It is painful a little bit also. I have a slight fever. Any sugeestions? I only applied a small amount 2 days.
