Circumcision will be slightly painful during the anesthetic, the pain is similar to that of an intravenous infusion, and patients are able to tolerate it. When local anesthesia is used, the anesthetic is injected into the root of the penis using a No. 7 syringe, which is the thinnest syringe inside the syringe, so the pain caused by skin damage is very mild, and there is hardly any pain with general or semi-anesthesia. The procedure is sleepy and the surgery is over when you wake up, so there is no pain during the anesthesia or the surgery. The patient can tolerate the pain. With the improvement of various circumcision methods, the operation can be completed within 10 minutes and there is no pain during the operation.
