I am so sorry to hear that your daughter has TN. I have it and the pain can truely be excrutiating. Besides the pain meds the only things that I found help to ease the pain was to eat only soft foods, talk as little a possible and try hot or cold packs. Tell her not to clench her jaw and to relax as much as possible. Eventually the pain will subside. Check out the site for the Mayo Clinic. Whenever I have a medical question or want to do some research that is usually the first place I look.
