How do I know if I have a DRY SOCKET, after my tooth is pulled?

You are certainly in the window to have developed a dry socket. The pain with that is located in the bone of the jaw beneath where the extraction happened, as that is the source of the problem. The socket in question is actually the tooth size hole in the jawbone that the tooth used to occupy. Extraction leaves a gaping hole, which the bone blocks off with a blood clot. Lose the clot, the bone dehydrates- the "dry" part of the dry socket. You did not mention the types of medications you take, but it's highly possible you have either a drug interaction or are simply taking way too much. Back down on the pain meds, Sparky. Take one or the other, not both- until you clear it with your dentist. Call the dentist to be seen ASAP. Meantime, make yourself a nice hot cup of regular tea. Nice and strong, and squeeze the bad until it runs nearly clear. Put the teabag on the spot that hurts, and chomp down lightly. Drink the tea, and let it pool in the cheek pockets- the tannic acid in the bag and tea, plus the heat will give you some relief until you can be seen and treated. And don't take more of those two medications- just pick one. That should keep you from seeing blue headed goat people, or any other strange things. And call the dentist- a little specialized packing job ought to see you done just right.
