Wavegeek, a lot of my early episodes of TN sound like what you're dealing with. Sadly, I had a lot of root canals and lost a lot of the root canaled teeth because the pain kept on being unrelenting. I also took alot of antibiotics for suspected sinus infections and had several CT scans which showed no sinus issues. Finally, I was diagnosed with TN, types 1 and 2. I have responded to some meds, but I had to come off of them due to side effects. I hear your frustration, but one of the best meds for me was an antidepressant and they are known to work well for nerve types of pain so trying Savella doesn't sound off. Did the doctor tell you that all antidepressants need a few weeks to build up to a theraputic level and that you need to give them time? I do hope you'll find some relief as the unrelenting pain is really hard to handle.
