Yes, I had brain surgery 2 1/2 years ago due to Arnold chiari malformation. Since then the pain that I would experience all over my body has returned. The episodes are longer and more intense. I have been seeing a pain management doctor and he has been giving me epidurals to the neck and block shots to my shoulders since my muscles keep contracting. I'm taking vicodin, skelatin, and gabapentin nothing seems to give me relieve. I don't know what to make to do anymore!
