Had some stitches removed in front of, inside, and behind my ears today. Nurse told me I had to wash harder to remove the "stuff" "debris" "gunk" or "crud" that covered some of the stitches. I have been rubbing as hard as I can in those areas when I take my shower and wash my hair. Any suggestions from anyone here? She said only to use soap, but that doesn't do it. Should I grit my teeth and pull off the scab or whatever it is?
