Postoperative dressing should be left intact until visiting your doctor within 10-14 days post-surgery. If swelling is occurring in the fingers and is NOT responding to ice or elevation, loosening the outer ace bandage or dressing can bring relief. For some procedures (trigger finger, carpal tunnel, ganglion cyst) you can change your dressing three days after surgery you feel comfortable doing so properly. A new dressing may need to be applied to the wound on the third day after surgery. Do not get your wound wet until seven days after surgery. Do not immerse the wound in water.
