The way the RO explained it is that the sag is due to the cancer that was in his neck (it was a very very large mass) invading some nerve, which he called by name by I can't remember it right now. He has had continuing problems with severe nausea and vomiting and the RO didn't think he could handle physical therapy at this point. The more I think about it, maybe we should at least request an evaluation right now.
