Whether boil incision and drainage will be accompanied by significant pain is objectively analyzed based on factors such as the different severity of local infection, whether the anesthetic range during local anesthesia is extensive, and the different degree of pain tolerance of the patient himself. I. If the patient has a strong tolerance for pain, and the anesthetic range during local anesthesia is relatively large, the patient’s local infection is relatively mild. The local pain is relatively mild, and most patients can tolerate it completely. Second, if the patient’s pain tolerance is poor, the local infection of the boil is more serious and the scope of local anesthesia is larger, and the infiltration effect of the anesthetic is poor during local anesthesia. In this case, boil incision and drainage is often accompanied by significant local pain. Some patients often cannot tolerate it, and it does not completely remove the local inflammation and does not allow for a quicker recovery.
