Hi,I am Dr. Shanthi.E (General & Family Physician). I will be looking into your question and guiding you through the process. Please write your question below.
My son skinned his knee a week ago and it became infected. I was able to clean it out and it has started to heal. Then a small blister appeared below it. The blister broke open and I cleaned it and put neosporin on it. It now has a larger blister around the edge of the original blister and the original blister contains pus.
