I developed a dizziness problem after taking suprep prior to an colonoscopy. It came and went but caused me to fall and whiplash my neck, which made it increasingly worse. Then after cataract surgery, I developed diplopia when I look at an object straight ahead and turn my head to left or right. That required me to wear prism glasses, which made my depth perception worse and caused me to fall again, which really whiplashed my neck and multiplied my dizziness and balance problems and sent me to a neurologist for help. Hr gave me an MRI of my cervical spine which showed serious damage to my C4 - C7 discs. As a result, I was evaluated by a neurosurgeon at Mayo, who will perform a ACDF in a month. My neurosurgeon did not think my cervical spine problem could be causing my diplopia, but we have decided to have a cardiovascular surgeon evaluate me to rule out the possibility of my head twist to the side could be blocking a vein or artery carrying oxygen to my brain.. Will let you know if anything turns up to explain that problem.
