Mole removed by shave excision/cauterized- is it healing or infected? (photo)

From your picture and what you described, it does look like the area could be infected.  The spreading of any redness,a malodorous discharge, and increasing pain are warning signs not to be ignored.  Please speak to your doctor right away and have the area examined.

Since you're concerned, I recommend following up with your cosmetic dermatologist and for after care recommendations. I recommend Silagen + Bioshield to promote healing. See an expert. Best, Dr. Emer

Wound require a certain amount of inflammation in order to heal. From your photographs, it seems that the amount of redness is more than expected and may represent and infection. You should probably call your doctor.
