Sorry to hear about your sister-in-law! Oh, I hate it when people I know have symptoms of TN! They have no idea what they may have to deal with! At least you will be able to be helpful and have been by telling her to see her doctor right away. The pain can escalate fast. Best to get ahead of it, then it is more manageable.

Hope your reduction of meds goes well. When will you be off that medication? Then you will still have Tegretol to get off, right?
