Why is there a hard lump on the penis after circumcision surgery?

Hard lumps on the penis after circumcision surgery are usually caused by local scars, hematoma, inflammation and infection.

Circumcision surgery usually results in local wounds. If the wound area is relatively large, it may cause local scar hyperplasia and hard lumps. If necessary, laser treatment is required according to the doctor's advice to promote the scar pigment to fade and blast out of the body.

During the recovery period, congestion at the wound site may cause local hard lumps. If the symptoms are mild, they can usually be absorbed and improved on their own.

Improper local care may cause inflammation to invade and cause local swelling and pain, or a hard lump may appear.
