They do work but he has 5-6 per day and we can't get enough shots.
He did two courses of prednisone, has tried Depakote, Verapmil, nerve block, lidocaine, lithium, methergine, emgality plus more I can't remember. He is preferring the cold to the shots, but it is not sustainable. He's had these for 20+ years, we are working with a headache specialist but do truly appreciate advice from this forum.
thank you
