I am on day 7th, woke up and my teethed are chattering when I am in pain? Like real bad. My doctor has had me on Tylenol 3 but it wasn’t working very well for my so he put me on fentanyl patch bit doesn’t seem to be kicking in and if it is doesn’t seem to be good job? Is the patch going to help.? I am so tired, don’t sleep much, have only eaten mash potatoes and applesauce, my mouth, jaw, Teeth, tongue, hurts so bad. At night is the worse..... drinking water is the hardest but I make myself.....
