Hi there and welcome. Sorry to hear what you've been through!
Did you try good moisture chambers and if so any benefit at all?

You will get similar reactions from all but a few specialists. This is new territory in ophthalmology and very few have ventured there. My guess is it will be many years before some of the BFS/Dr. Rosenthal's views on corneal pain gain acceptance from the mainstream: but it will happen when proper research is completed. Takes time.
They suggested a new therapy called the scrambler. I guess they place electrodes around your eyes and it's suppose to "scramble" the pain signals the nerves send. It's only for the neuralgia NOT for the dry eye.
It's a very new concept and as you found is just starting to be tried for unresponsive corneal pain.
