A thorn in the hand can be removed with tweezers or cut with specialized instruments. 1. If the thorn is relatively small and only on the surface of the skin, you can use sterilized tweezers to remove the thorn by following the wound. Before the operation, you can soak your hands in hot water to soften the epidermis and make it easier to remove. 2. If the stinger is deeper into the skin and can’t be removed by the above method, then you need to go to the hospital and make a local incision to remove it, and then bandage it after removing it. Before and after the above operation, it is necessary to strictly use iodine povidone or other medical skin disinfectant for disinfection, to ensure the hygiene of hands, instruments and wounds. After removing the splinter, tetanus injection is also needed if necessary to avoid infection. All of the above operations need to be carried out in the hospital by professional doctors.
