My 24,y/o son was handed a hot clothes iron and burned the pads of his fingers. They have turned white and blistered. He has been keeping his hand under running cold water. I first gave him motrin 600 mg for pain then went to the pharmacy and bought a 2.5 % lidocaine gel for burns. It didn t help. I also bought neosporin and gauze to wrap his fingers when the pain subsides. What else can I do ? A friend of mine recommended silvdene cream but its prescription only.
