Found this when I googled cochlea and migraine,lots of information came up.Posted on m.org and thought I would put it up here too.Sorry if you already have this info.
Thanks for the post James. I’ll move this into the General Discussion area for a bit where more people will see it.

James & Scott - thanks for posting that… very enlightening and validating for all of us that know that all sorts of inner ear stuff happens with migraine. Hopefully it’s one step closer to better understanding and collaborative treatment from the medical community.
