I have had vision problem for several years now. I have one fully dlated unresponsive pupil ad the other one is sluggish. Nobody can tell me why but it does cause problems with sun and dark. Virtually blind when it's dark. Blurry vision is a common occurrence too. Difficult to move from close work to distance and vice versa. Now getting migraine type symptoms.
Getting fed up with all the different manifestations of fibro. Feel like a hypochondriac some days.

I am sorry to hear. I know when I get migraines, I get what they call an "aura" about 30 minutes long before the migraine pain comes. During that time, I am unable to see, it is like a film over my eyes. I also get bad balance issues at times and tremors at night sometimes. I hope you get some relief.

I have never fainted, however do experience the vision issues, tremors and balance issues right before a migraine strikes. I have what is called chronic complex migraines...I think it is part of fibro. I hope you feel better soon

Cluster headache or ms is my guess.

It could be MS
