If the stinger is very small and deep, you need to go to a regular hospital, and the doctor will cut the skin under local anesthesia to remove the stinger. If the stinger is so small and deep that it can no longer be removed with tweezers or needle holders, you need to go to a regular hospital in time to seek professional help from a doctor who will give you local anesthesia to anesthetize the area where the stinger is located, cut open the skin, and pick out the stinger. Then thoroughly clean up the wound, suture and bandage. If the splinter is metal or heavily contaminated, tetanus immunoglobulin is needed to avoid tetanus infection. During the recovery period, the wound should be kept clean and dry with a light diet and abstinence from smoking and alcohol. A small but deep thorn in the palm of the hand should not be taken seriously and professional medical help is recommended.
