Whether a patient with pus under the scab should be uncovered depends on the severity of the pus under the scab, the patient’s own healing ability and other factors for objective analysis. A. If the patient’s suppuration under the scab is very limited, the local skin does not appear red, swollen, hot and painful and the patient’s own healing ability is strong, there is no need to uncover the scab. Topical application of Ruyi Jinhuang cream or vital iodine gauze, as well as oral administration of amoxicillin and levofloxacin tablets to promote faster absorption of local infection, thus achieving better treatment results. Second, if the patient has a large amount of fluid and pus accumulation under the scab, as well as local redness, swelling, heat pain, etc., and the local skin temperature is obviously increased, the patient’s healing ability is poor at this time, and the simple use of drug therapy is not able to make the pus accumulation under the scab absorbed more quickly. Patients are advised to uncover the crust to remove the fluid and pus under the crust and strengthen anti-infection treatment, which can promote faster recovery of the local wound.
