A little pain three months after circumcision may be caused by localized keloid hyperplasia, non-detachment of the material used in the surgery and the formation of localized scarring. 1. Localized keloid hyperplasia: scarring is prone to localized keloid hyperplasia, and scarring can lead to shrinkage of the foreskin. When scarring occurs, the foreskin will become embedded in the glans, causing localized pain. 2. The material used in the surgery is not dislodged: the material used in the surgery is not dislodged, for example, the anastomosis needle is not dislodged, and there is a thread knot in the foreskin, which leads to the reaction of the discharge. Dislodged thread knots, or aids that have not been dislodged, need to go to the hospital for further examination. 3. Local scar formation: local scar formation, accompanied by neuropathic painful nodes have certain pain symptoms. Circumcision pain has not been relieved, need to pay attention to, to seek medical treatment in time, under the guidance of professional doctors to deal with and treat.
