Scrotal pain after varicocele surgery may be caused by obstruction of blood supply, inflammation, pulling and so on. 1. Obstructed blood supply and reflux: because of the surgery, the lymphatic blood supply and reflux is affected, and the lymphatic fluid takes the opportunity to enter into the tissue, which makes the scrotum edema and squeezes the nerves and produces the scrotal pain. 2. Inflammation: After varicocele surgery, due to improper wound care, infection may occur and cause inflammation. As a result, there will be redness and swelling at the wound, scrotal pain and other uncomfortable symptoms. 3. Involvement: During the surgery, more tissues are affected, and the spermatic veins will be involved when the patient stands up and moves around after the surgery, which will result in scrotal pain, and the situation will be better if the patient lies down. If there are other reasons for scrotal pain after varicocele surgery, patients should go to the hospital in time for postoperative review to clarify the cause of the disease, and then deal with it under the guidance of the doctor in a timely manner.
