I haven't looked at my MRI/MRAs in a while, but my first electric shock of TN occurred when blowing my congested nose.
What type of pain are you experiencing? The TN nerve has many sub-branches that touch many parts of the face. A good resource for diagrams of the TN nerve is the online Greys Anatomy book on bartlebys.com, you can google it.
Have you posted your question in the Experts area?
I just got the results of my MRI after going thru TN and carbamazipine being the only drug that stopped the pain. The MRI showed marked left maxilloary sinus disease which i have no clue about but is the same side of my face that the TN effected. I see an ENT on Dec 12.
