Went to Dentist will be a week tomorrow my face still swollen, tender to the touch including the upper lip and left side of my nose have had root canal befor but this has never happened, if I press on my face it sounds like water is moving around. My main concern is they used a medication to clean out the canal called MTAD/Biopure when he injected it "omg" my face felt like it was on fire on that side the dentist said out would be swollen for maybe a day and I may get what looked like a black eye, well the black eye never happened but the pain and swelling is still there including feels like a sinus headach along with my nose feeling like I cant breath right and eyes feel irritated, a bad taste that feels like I burned my tong on something hot. Has anyone had this happen and what can I do to feel better, tried ice,antibotics,ibprophen nothing is helping. HELP
