Your incision is closed using a number of sutures below the skin surface. When you remove the outer dressing (see bathing instructions below for when to remove the dressing), you will find a special ribbed tape covering the incisions. The ribbed tape will fall off on its own.
All patients will have swelling and some black and blue discoloration at the incision site or around it. The swelling does not mean your umbilical/ventral hernia was not repaired. This swelling and discoloration is normal and will resolve over the next several weeks to months. Sometimes this swelling can feel quite hard, and may seem to appear several days after surgery.
Many patients have used Arnica Montana, either as a gel or orally, to reduce swelling and bruising after surgery. Arnica is a safe, homeopathic medicine that works well in many patients. Most natural food stores will carry it.
