For the past few months, I've had a mild headache most days. I thought it might be that I needed glasses, so I went and had my vision checked, which was 20/20, but the they noticed my optic nerve was inflamed and referred me to an ophthalmologist. Then I started having my vision cloud over and turn gray whenever I stood up too quickly. The ophthalmologist definitely noticed the optic nerve was considerably inflamed, and my right eye showed signs of it beginning. He sent me for an MRI which came back clean, so he could not figure out a cause or treatment, and referred me to a neuro-ophthalmologist 3 hours away since he would be able to find the cause. That doctor was unable to figure out a cause except for possible stress. He then referred me to a neurologist, which I have the appointment for next week. Anyone have any idea what to expect, or any suggestions? Thanks for your help.
