Hello everyone I've been suffering for a little over 2 years my neck gets really sore off and on I deal with this constant head pressure and lightheaded spells that make me feel like I'm going to faint I have frequent headaches in the back of my head my vision goes blurry off and on and my memory has been getting worse and worse. I had a MRI of my head around 2 years ago which my neurologist said was ok but I had a ct scan about 2 months ago of my head and it said something about my cerebellar tonsils were extending toward the foramen magnum but it said they are not thought to be extending below the magnum. Should o get another MRI? I also feel short of breath a lot to don't know if it's related to CM. I've had tons of tests for just about everything else with nothing showing up
