During surgery, pain is prevented by the use of local anesthetic injections. Typically, the anesthesia loses its effect 3-6 hours after surgery is complete. Tylenol alone usually takes away further pain.

Great care will be taken to seal all blood vessels during surgery, and a pressure dressing will be applied before you leave our office. These two measures should prevent any significant bleeding. Occasionally, post-operative bleeding occurs. Those individuals who are on blood thinners, drink alcohol before or after surgery, or who stretch or traumatize the wound within the first few days after surgery may be more prone to this type of bleeding.

If bleeding through the pressure dressing occurs, apply firm, even pressure with your hand for a full 20 minutes. If this does not halt the bleeding, call our office at (650) 326-7222 or go to the nearest emergency room.

Bruising around the operative site is common. These will disappear similar to other bruises. The eyelids and cheeks are particularly sensitive.  Bruising of one or both eyes may occur, even when they are not directly involved with the surgery.

All wounds will have some drainage. This should steadily improve each day. Increasing drainage can be a sign of infection.

Any time the skin is broken, by trauma, surgery, or other causes, an infection is a risk. Fortunately, close attention to wound care largely prevents infection from occurring. Non-infected wounds will gradually become less red and less painful each day after surgery. Infection is signaled when redness and pain increase. If you suspect an infection, call us immediately. Infections are treated with antibiotics.

One can expect some swelling (edema) the week after surgery. Swelling will be worst the first two to three days after surgery and should gradually resolve. Applying ice and sleeping with the surgical site elevated is helpful in minimizing post-operative swelling.

It is normal for surgical wounds to become red. The redness is part of normal wound healing. Increasing redness spreading out from the wound can be a sign of infection or an allergic reaction. If you suspect a problem, please call our office.

Scars always result from surgery of the skin. Our intent is to minimize the scarring and provide the best possible cosmetic outcome. Scars continue to heal and mature for 12-18 months after surgery. On occasion, a second procedure can help disguise the scar further.
