Had planar mole removed and now I can barely walk. (Photo)

About 4 days ago I had a mole on the bottom of my foot removed. I was instructed by my doctor to wash my foot about 3 times a day and apply an antibacterial cream and cover it with a band-aid. I have been consistent with that for the most part, changing my band-aids and applying Mupirocin. On day three I woke up with foot pain and had difficulty walking when I could walk fine before. I am worried that I may be infected and that is where the pain is coming from. I have attached photos of day 3.
