I just got a set of brain/ cervical spine MRIs done. The radiologist report says the cerebellar tonsils are a bit low, but there's no herniation. I experience headaches, dizziness and feeling like someone's squeezing my brainstem when I'm standing up. I also have severe Central Sleep Apnea. Does it look like I should pursue the Chiari angle, or am I barking up the wrong tree?
