Is green puss on my frozen mole a concern?

An In Person evaluation is needed in order to determine if there is an infection present, I suggest following up with the physician who performed the mole removal. Best, Dr. Emer. 

If you are having a green discharge from your surgery site, it probably is infected.  You can begin by using hot compresses on the area for 5-10 minutes twice per day.  And you should see your dermatologist or surgeon for antibiotics.
