I have ad sever headaches, nausea, vertigo and fainting spells for 9 months. 8 months ago the hospital informed me that i have a 6.8mm Chiari. Since then i have been passed between health professionals testing my heart, epilepsy, and everything else under the sun. Been to the neuro surgeon a few times and he jsut keeps saying wait and see if they find anything else first. Really getting to the end of my rope. should i see another neurosurgeon?
