When mine started, I thought it was a bad tooth, so I went to the dentist. As I was having my tooth
extracted, I felt sharp stabbing pain
in my upper gum area.
After this, it just got worse. It felt as if someone was prying my upper teeth out with a crow-bar. Eating and talking, as well as stress brought the pain on.
I do have an underlying neurological disease as well. My neurologist placed me on gabapentin or Neurontin for the neuropathic pain. This greatly helped relieve the TN.
