Thanks for your query. Wound management is very important and should be done properly. Dont wash with soap, plain water or normal saline is recommended for cleaning the wound. Avoid Neosporin, because it can lead to allergic contact dermatitis
on adjoining areas. Hydrogen peroxide
or Eusol dressing is ok, followed by application of antibacterial creams like Mupirocin or Fusidic acid
etc. Change the antibiotic i.e. Bactrim DS to broad spectrum antibiotics like Cephalosorins etc because the former antibiotic sometimes causes drug allergy like itching etc.
All needs to be done under supervision by a dermatologist
