It very well could be trigeminal neuralgia, but here is my story!! I had root canals done on every tooth in my mouth just about. Finally in 2015 my teeth were removed and I received 7 dental implants. I started with constant pain and throbbing where one implant was put. I was checked and rechecked! Nothing wrong. I was diagnosed with MAC, a lung disease and began medication for that - which by the way has been linked to dental procedures and dental water supply! My one sided face pain continued. My eye hurt so badly. My husband couldn’t get over how my face would swell. I’d be in bed all day. I even missed one of my children’s weddings!! 🙁 Long story short fast forward to 2022!!! I had a complication from a lung procedure and ended up spending a good portion of time in the hospital with a chest tube. New diagnosis!! Invasive aspergillosis fumagatos with pneumonia. I was placed on a drug called Vfend, and within a week those face headaches stopped!! I am convinced the Aspergillosis was in my sinus as well as in my lungs. I have no other explanation for that significant a cure. Don’t give up. Your face pain could be caused from something somewhere else in your body! I literally spent years in agony. Good luck to you. irene5
