Suggestion: It is normal for prepuce surgery to have a little edema, redness and pain. Don't worry too much. The erection must be controlled after the operation, otherwise the wound will easily crack and the healing time will be prolonged. When the erection is not good, a basin of cold water goes down and a toilet is on your face. You must protect the wound. The prepuce operation is not big but the position is important. I wish you a speedy recovery.
