Im on anti biotics for four days and its worse at night. What is going on and what do I do.. No one can seem to tell me whats going on and I can not get rid of the pain ??? [/INST] Dear friend. Thanks for sharing your concern. Your history suggests that you have got root canal treatment done. Which is still incomplete. Please give me complete history, regarding your root canal. Your present pain is due to infected canal and infected pulp tissues there, causing pain. It can be relived by painkillers temporarily, but you need to see your dentist soon, so that infected pulp tissues can be thoroughly removed, canal can be prepared and then saturated (filled) aseptically. Meanwhile, continue with your antibiotics and painkillers. Do antiseptic mouth rinsing. Hope it helps. Thanks. Take care. </s>
