After circumcision, the iron nail (skin nail) is generally discharged in the form of natural shedding and surgical removal, which needs to be analyzed specifically according to the patient’s situation. 1. Natural shedding: after circumcision, patients will generally use the nail to nail a circle around the circumcision wound, to play the role of anastomosis and hemostasis. Under normal circumstances, most of the two weeks or so will fall off naturally, there are some patients due to the nail too tight or serious adhesion of the circumcision wound, it takes a month or even longer to fall off naturally. 2. Surgical removal: if more than one month than the nail has not fallen off, you should go to the hospital in a timely manner, under the operation of a professional doctor to remove the nail. It should be noted that, after the circumcision should be sterilized under the guidance of the doctor, and wear loose underwear in daily life, to avoid back and forth friction between the penis and clothing, resulting in secondary injuries. When discomfort occurs after circumcision and is not relieved, you should consult a doctor in time and deal with it positively under the doctor’s guidance to avoid delaying the condition.
