@californiazebra @fdouglass Your case reminds me of mine. I posted under a few discussion groups (ENT, Covid, Neuropathy) to see if anyone can relate. I have the same issues where my nose and teeth have constant pain. Sinus pressure/pain with clear scans. That is interesting how carbamazapine works for you to bring the pain level down if that's the case I would recommend going back to Neuro. Carbamazepine did nothing for me. I tried a trigieminal nerve block as well. The only thing that helped was 6 weeks post sinus surgery I felt better but the pain came back so the doctors are thinking its not sinus related. I can understand your pain. I wish something worked to relieve my symptoms so I can have my life back.
