Thank you SO much for all your emails and well wishes!
My brother hasn't been for the scan yet - he went to the neurologist and because of the financial concerns, the doc said it's not imperative that he goes for the scan, he can just monitor my brother over the next few days.
I don't like that idea since instead of finding out if there are any problems through a scan, they'd be waiting to see it physically!
Anyway, the up side is that although his eye still hurts, he's feeling less nauseous and my Mom says he's sounding perkier.
