Had dental procedure six days ago. I am resistant to the local anesthetics and required quite a bit more ( 7 injections) to eliminate pain, was a little 'foggy' when I left there. ( this resistance is normal for me). I had a perio cleaning, a molar extraction, and a bone graft implanted. The dentist closed with stitches. Because I had a perio deep cleaning on the other side of my mouth and have an aortic valve surgery scheduled in a month, I have been on amoxicillin for 2 weeks and just finished that today. Note that I do not get headaches. Ever. After the extraction, I have not had pain or problems with the wound itself , nor fever or sickness, however, I have had a mostly-pressure headache constantly for the entire week, and it does not seem to be lessening. It is not sharp like a migraine must be, but I also seem to have a light-sensitivity going on as well as the tension-type headache.
