question: I recently had a root canal last week on my upper pre-molar right side, now a week later I am still experiencing tingling, burning sensation on the affected tooth, pressure on the tooth behind it and overall feeling of jaw soreness. I have also experienced severe migrianes that appear out of nowhere and is different than a typical migraine that I have experienced before. It sends shooting pains up to the top of my head. I am on an antibiotic and painkiller/anti-inflammatory and nothing seems to help relieve this. I dont know what to do anymore with this constant pain...
