Yes, TN or TN-like issues. I have it on both sides and all three branches. I have been told by docs in Mayo and Oregon that they would not touch me with a 10 foot poll. So I completely understand the shuffle and dump by doctors. Try to find a pain management doc or a neurosurgeon who understands facial nerve pain. The pain pump is not usually prescribed for new diagnosis since they have to try the cheaper (meds )route. My unit came in just under 250 thousand. It's a no fuss unit that is filled every 90 days in my home.
