How do I treat a fairly severe steam burn on the top of my thumb. I have been using Neosporin for about 5 days and I just recently became aware that I may be damaging my kidneys by using Neosporin on such a deep wound. My concern is not a scar, I want to avoid an infection so I dont think the advice Ive gotten, which is to use Aloe is going to do much good. I have kept it covered almost the entire time with the exception of in the shower and then I try to avoid direct contact with the full blast shower steam. Initially I did rinse it under running cool water for 5 minutes. It does not have blisters, the pain has gotten no better no worse and the pain is moderate not severe it is also not constant. Although I do not feel heat coming from it nor has it swelled or blistered, it is growing increasingly red of various shades. The burn is not quite the length of my thumb but close. When the steam hit my thumb initially, I literally watched a layer of skin fall off. It looks deeper than a single layer but I cannot tell. What can I do to promote healing without infection? Also based on the information I have given would you guess without actually seeing it that there may already be infection setting in? I will also point out that I just finished 10 day round of amoxicilin two weeks prior to this burn. Is there any chance that may help prevent infection despite being finished two weeks prior? Also I do have Neosporin on it now under the gauze, should I wash it away?
