The description you have provided points at two possibilities. The first one is that you have managed to break the stinger, thus leaving one half of it in your finger. If this is true, you should know that you will not be able to find relief in any way till the stinger is completely taken out of your body. In fact, if a couple of days or so have passed, you should go to a doctor immediately. The reason for this is that if a sting is left inside your body, it may also turn toxic and affect you adversely. It is always wise to get it medically taken care of. This will also provide quick relief. In all probability, the doctor may make a small incision and take the stick out manually. This is rarely painful, as local anesthesia may well be administered. But the bottom line is that you should not ignore the problem any more. The second possibility is that you simply have delicate and sensitive skin and therefore the swelling is taking a while to subside. Sometimes, stings that are dangerously painful can take up to a few weeks to heal. Not that this is common, but it is also not unheard of.
Ice packs are only momentary in providing relief in your condition. In fact, you should avoid using them. This is because when you apply ice, the area is temporarily numbed, and the circulation also slows down to a large extent. Once the ice is removed, the circulation returns to normal and this causes waves of pain to afflict your finger. The best thing to do is to keep your finger elevated. What typically happens is that we tend to let our hand dangle. This makes the blood pool at the fingers. When there is an injury, this only causes a slowdown of circulation and also healing. This is best avoided. An excellent remedy to draw out excess pain and swelling from bites is to use Fuller's Earth. This product not only cools the skin down, it also helps to heal the injury. Make a paste and apply this to your finger. This should go a long way in helping you. An old wive's tale also dictates that you can rub an iron nail around the area of the sting. This also supposedly helps with the swelling as well as neutralizing the venom, if there is any still left over in your body.
