Once the thorn is embedded in your son's foot like this it is difficult for you to remove it. You really need to open the skin covering the thorn with a sterile needle and then remove the thorn with cleaned and sterilised tweezers. As your son will not allow you to do this and also the thorn is not festering,it will be uncomfortable if it stays in place. It would be best to ask your GP to remove the thorn from your son's foot.
