Yes I have if nerve tigger helpful though psinful
I had greater occipital nerve block. The actual procedure was fine. Very strange feeling after as I couldn't feel the back of my head. For me it didn't work. But what doesn't work for one can and will work for others.
I get a nerve block in between my botox injections if I need it for my miagrine. I can have one every 3 weeks if needed.
