that is an allergy to the adhesive and possibly latex. could also be allergy to bactracin(type of neosporin). i have all three. allergist can do a test for them.
my son got a scrape on his elbow. there appears to be a rash where the bandage was. could this be an allergic reaction? . at first they were just bumps but now they appear white almost puss like. i do not know what type of bandage was used since this happened at school.
