I need a good referral for a physician versed in diagnosing and treating TN. For months, I have suffered severe pain lasting up to six hours (TN2?). At first, I thought it was a toothache. The dentist was kind, but did not help. A neighbor told us about TN and after reading, the location of the pain and nature of the problem fits. In looking at various web sites, it looks like Drs. Samuel Barnett and Jonathon White are affiliated with UTSW. Can anyone share information about working with either one? Thanks in advance for any help.
