I"ve been dx with cerv. spond. by a neck x ray, my insurance didn't approve a neck MRI they want me to do 6 weeks physical therapy. But when I bend my neck down, my vision becomes blurry ( been to eye dr. eyes are ok ) and sometimes it feels like my eyes go from side to side. So I was wondering if anybody is familiar with cervical nystagmus ? that' s when there is a compression of the arteriae vertebrales. I'm afraid with the physical therapy it will become worse. Should I see an ENT also ? my neurologist sent me for the MRI , and I will have MRI of the brain, but not the neck.
