"i would go to the doc 3 days in a row each week, every week,,,, he would take a long q tip, soak it in lidocaine, and insert it up into my nasal cavity, about 3-4 inches, and leave it there for 30 mins,,,, . no luck, well on day three of my first week while the qtip was in my nose i got hit, bad, one of the worst of many attacks i have experienced, not to mention being in public, needless to say i said F-that
with tears in my eyes and a q tip protruding from my face"-(paraphrased)
This is not how this is being done now(at least not everywhere) The sphenopalatine ganglion block is done as an injection under X-ray directly into the ganglion. The block is a TEST!
ONLY if the block works will radiofrequency rhizotomy be considered.
  I'll let you know more in a few weeks.
p.s.As BobW can tell you,she has indeed tried EVERYTHING else leading up to this.
