If the usual weak coronary sulcus is exposed

Normal! The foreskin operation is to remove the foreskin completely, so that the glans penis and the coronal sulcus are exposed in peacetime. If there is no swelling and pain in the protruding part, it may be lymphedema, which is normal. After two months, the swelling will gradually decrease. If it hurts, go to the hospital at once. Maybe the wound is inflamed.
