I had my lower right premolar extracted on tuesday at around 5pm. When the anastethic wore off I was in unbearable pain, so I took a paracetamol and held a cold compress to my cheek and the pain went away. The next day I woke up with no pain. However as the day went on and ever since I have had pain in the jaw, a dull ache that sometimes twinges in my chin and occasionally radiates to my ear, and on one occasion my temple. Before today I controlled it with two doses of cocodamol and 200mg ibuprofen a day, today I have managed on two 200mg ibuprofen. It just feels like the pain will never go away - it's not getting worse, but it flares up at night where it is usually manageable in the day. Is there something wrong? (additional info - I broke my jaw 2 months ago and it just finished the healing process before the extraction; also the extraction site looks healthy, gums slowly healing over a black socket. Bathing in salt water 4 times a day and brushing gently twice a day as normal.) Update - I have just realised I have to pay and I am a poor poor student in London who barely has enough money to eat but I am so worried about this pain, pleeeeeease help me :-(
