Could well be a dry socket, I've had 2 teeth out up to now and 2 dry sockets. Look at the hole, if there's red blood in it then it must be something else, if it looks like there's nothing in then its could be a dry socket. Dry socket = 2 weeks of pain like you're experiencing now. Paracetemol and Ibuprofin can be mixed = a dose every 2 hours. With my last one I had 10 days of pain, went to a wedding, dranks lots of alcohol, woke up with a new blood clot in place and subsiding pain. I don't think that approach is medically advisable however.
