Hi there, so sorry with everything ur going through. I recently had a vp shunt placed in the right ventricle of my brain due to a cyst on midbrain filled with protein blocking the aqueduct leading down to the spinal cord causing increased icp. I also however was experiencing some of the same symptoms you describe. Oddly enough, I also was diagnosed with Chiari malformation with syringomyelia. I dont think my surgeon felt that was the main problem. I hope that everything gets back to normal as soon as possible for you.
