Sorry I have been very active on the forum lately, I am throwing everything at this before my sick leave expires for good.

How can we tell the difference between PCS and MAV? The more I read about MAV the more I feel that there is a lot in common, and start asking myself "Do I have MAV?"...

I might be wrong, but it seems to me that sensitivity to screen light, moving objects on screen, scrolling, etc... is not as common in PCS patients as it is in MAV. Maybe I am wrong.

I wish there is a way to find out and dissociate...
Two differences I see: (a) convergence insufficiency seems to be way more common in PCS then MAV (b) vertigo -- which I don't have -- seems to be more common in MAV, but not .

I really don't want to be put on MAV drugs and their nasty side effects (I tried two for only couple of weeks, couldn't handle either). But if that is what I have (developed following the concussion), then maybe I should be thinking more seriously about it.
