Lymphoedema and associated swelling in the penis is an expected complication of circumcision. The length of time that it lasts after circumcision varies and is unpredictable, but it is not uncommon for it to last many months.
Blood is supplied to the penis by arteries deep within the penis. Blood is returned to the heart by veins in the foreskin. Circumcision severs those veins, so blood has difficulty in returning to the heart. This causes a buildup of lymphatic fluid in the penis.
There does not seem to be any satisfactory treatment for it except patience and time.
