My dad had a back operation last week! but his wound keeps on bleeding and the nurse was worried about the bleeding!

Surgical follow-up: Surgeons (any type of surgeon) follow-up on their patients until they finish healing. The surgeon knows what parts of the body were cut, moved, removed, put back together, and sealed in with the final sutures. The surgeon is the person to contact (or the doctor covering for the surgeon) whenever there is a problem with the surgical wound or procedure. It's time to contact the surgeon.
