Whether or not the incision and drainage of boils will be accompanied by significant pain will be objectively analyzed based on factors such as the severity of the local infection, whether or not the scope of anesthesia is extensive during local anesthesia, and the patient’s own tolerance of pain. I. If the patient’s tolerance to pain is strong, the scope of anesthesia during local anesthesia is wide, and the patient’s local infection is relatively mild. The local pain of the boil incision and drainage is relatively mild and can be tolerated by the majority of patients. If the patient’s tolerance to pain is poor, the local infection of the boil is serious and the scope of the boil is large, and the infiltration effect of anesthetic during local anesthesia is not good. At this time, if the boil is incised and drained, there will be obvious pain in the local area. Some patients are unable to tolerate it, and it does not completely remove the local inflammation, and does not enable faster recovery.
