I must admit, I am a little confused. I seem to keep running across people who get AD from GK. They were trying to treat my husband's AD with GK. And they told us there were absolutely no side effects. Maybe it depends on where the GK is? As far as we were told, he was the only person with AD who had had GK to ablate the sphenopalentine nerve bundle. All the rest (about 16 or 17 as of last January) had had it for atypical facial pain. It did not work, but it also didn't seem to have any side effects--for him.
