Drainage surgery can be recovered in a week or so, but this cannot be generalized and depends on the severity of the wound and the recovery. When the incision wound is small, and timely cleaning and targeted treatment, so that the wound recovers well, without the phenomenon of wound pain and infection, the wound recovery time is relatively short, in most cases can be healed in a week’s time. However, if the wound is large, the recovery time will be extended. If the wound becomes infected, painful and swollen during the recovery process, the healing time will be prolonged accordingly. It is recommended to carry out the cleaning work and postoperative recovery work under the guidance of a professional doctor, and not to use medication privately to avoid causing stimulation to the body, which is not conducive to the healing of the wound.
