Hi! I'm 18 and I've not been diagnosed with CM, but I experience many of the "common" symptoms which makes me suspect that something is off. Ringing/pressure in ears, pressure/feeling faint when laughing (if I laugh alot I'll get a headache that lasts all day and my head feels like it's about to explode), tingling in one side of my face/thigh, suddenly feeling weak and dizzy. I remember reading an article on a woman with Chiari, who was told by her doctor that if she laughs too hard she may die? Is this really true? Or rapid movement of the head? I went to an ENT for my ears, he found nothing but he said my neck muscles were tight, so he gave me a number to a naprapathic doctor but I haven't seen him yet. My doctor doesn't think I need an MRI or CT scan... I don't know if she is familiar with Chiari, so I don't really want to walk into her office and demand a scan just because I "think" I have CM. What should I do?
