Hi Cagon,
I feel sooo bad for you because I was once in that particular hell! I couldn't take the oral meds so I had 2 mac degeneration surgeries where they put teflon on the blood vessels so that the nerve could be protected. Some say it works. I had 2 that didn't. I had a gamma knife procedure that didn't work either. So after 5 years of horrible stabbing pain I finally asked for a Rhritzomy....where they finally cut the nerve so that they didn't touch anymore aganist the blood vessel. It is the only procedure that finally gets rid of TN.!! Your mouth is numb and there maybae some complication, but it beats the suicidal thoughts you feel when you get searing thunder pain stabbing thru' your face. Talk to your doctor about that option.
