Because something as little as a thorn embedded in your finger can cause an infection, the foreign object should be removed as soon as possible. An embedded thorn can be removed at home with little pain and little effort, and save you from a big doctor's bill.
Wash your hands with antibacterial soap under warm water, then clean the wound using soap and water. Don't press against the thorn and embed it deeper in your finger during this process.
Dip the tip of a sharp needle into rubbing alcohol to sterilise it.
Press the tip of the needle into the opening of the wound and pull up, breaking the top of the skin around the embedded thorn.
Sterilise a pair of metal tweezers with rubbing alcohol by dipping the tongs into the liquid.
Remove the embedded thorn with the tweezers, grasping the tip of the thorn and pulling it out gently.
Wash your finger with antibacterial soap and warm water, then apply antibiotic ointment to the skin after it's dry.
Clean the needle and tweezers with antibacterial soap and water if rubbing alcohol isn't available. Get a tetanus shot booster if your last shot was more than 10 years ago.
Seek medical attention if it is not possible to remove the thorn, or if the wound becomes inflamed or infected.
