If it takes a long time to stop the pain after being stung by a wasp, an objective analysis should be made according to the patient's different tolerance to pain and the severity of the injury.

First, if the patient has a strong tolerance for pain and is stung shallowly by wasps, and does not cause serious complications such as redness, swelling, heat, pain and bleeding in local tissues, the symptoms of local pain can be gradually relieved after 24-48 hours without causing serious complications.

Second, if the patient's tolerance to pain is poor, the wasp bites widely, and the local damage is serious, accompanied by obvious redness, pain, skin temperature increase, and even local inflammatory symptoms such as effusion and pus accumulation. At this time, it takes a long time for the injured tissue to recover. External use of Ruyijin ointment and strong iodine gauze can promote the absorption of local inflammation. It takes about 5-7 days for the local inflammation to completely subside and the pain symptoms to completely relieve.
