I was diagnosed with Chiari 1 (1.0 cm herniation) in 2003, and had surgery in 2004. Your symptoms sound very much like what I experienced for many years. It was by accident that my herniation was found. I had a neurological rx to Remicade and had MS type symptoms. I was finally sent to Neurology who did MRI. I definitely believe you need a neurologist instead of just GP to evaluate you. GP's are great but not for complex issues like this. Sometimes you have to get 'firm' with your docs and tell them what you want.And if that doesn't work, you tell them you don't think you are getting their best work and need better care.
