Very small thorn into the flesh can not be picked out we can first use iodine vapour disinfection, and then go to the hospital to remove. You can disinfect the wound by rubbing a disinfectant solution, such as iodine volts, and then put a small ice cube cold on the surface of the injured skin to reduce the pain, and then use a sterilized needle to pick the thorn out after 15 minutes. If we can’t see it and there is no obvious pain or redness or swelling, it’s usually okay and can be allowed to heal on its own without treatment after sterilization. If the patient has redness, swelling, pain, and this place has been unable to touch, we can consider going to the hospital to remove it surgically. You need to pay attention to the cleanliness of the wound skin, and should not touch dirty water within three days to prevent bacterial infection and affect the recovery of the wound.
