Ok to call doc. In general wash the wound with soap and water, pat dry, and hairdryer. Okay to call your doc for more wound care and follow up appointment. Okay to ask about antibiotics. Go in sooner if you develop fever or drainage.
Local hygiene. This shld have been covered by the doctor who did the procedure. Call him and get the answers you need.
Clean and antibiotic. Keep it clean and apply antibiotic ointment twice daily.
