HI Capri, You’re right. This is a “grey area”, to say the least. Of course, not having ever seen you, I have almost no idea of what is going on… If your chiropractor could FEEL something in your neck, it does sound like a disc may have been out of place, but that is pure conjecture. This is one of those things that “you just have to be there” to know! 😉 We have to be careful with our necks because of the potential for Chiari, especially with external communicating hydrocephalus, because of the risk of thrombosis (many of us have “thick blood”), so yes, we need to be very careful. I still wear a soft cervical collar at night time. Maybe I don’t need it any more, but it was so helpful before I started Diamox, that I continue to wear it to help keep everything lined up while I sleep. I even get nervous putting my head back to have my hair washed for a hair cut!! (Have you heard of ‘hair dressers stroke’ before?). I’m the last one to throw out an entire profession, though. Caution is the name of the game (and gosh, did you have your eyes examined?). When you go for your eye exam, a CAREFUL fundus exam, OCT, and even a VEP may be in order. Those can be very telling… Let us know? 🙂 Diana
