I would suggest seeking a second opinion. Of course my opinion is based on just researching for myself and looking at what others have had experienced. TN pain can be very weird and abnormal but like other disorders can only be diagnosed by ruling out others basically. Obviously your having an uncomfortable pain so something has to be causing it. I am not a TN expert but what you describe I have read some atypical TN patients describe that. Don't give up until you get an answer and trust me it could take time, but keep searching!
