It is not uncommon for post-extraction pain to continue like this, especially after a 'traumatic' extraction. You really should return to see a dentist (either your own or another) to exclude the possibility of you having a localised osteitis (dry socket). If this is the case, a sedative dressing can be placed within the extraction socket which will give you pain relief. Other than this there is little more you can do other than take analgesics, as you are doing, and be patient. The socket will usually heal eventually, though it can take time. Hope that it improves soon.
