KnockedOutMom,

Your frustrations are understandable but please try to not direct them at the doctors. If other doctors notice your frustration, it could work against you.

There are migraines that do not manifest pain. What the doc said about those vision loss episodes could very likely be correct.

"Brain clinic dr didn't seem surprised that they were of no help. "
This could just mean they considered your symptoms a challenge to diagnose and are not surprised the neuro-ophtho could do no better.

Plenty of us feel your frustration.

My best to you.
