This morning my brother wised up and drove himself to the ER. Yesterday they ruled out pancreatitis, but last night he couldn't keep anything down - even water. He's lost about 35 pounds thus far, and his color is off (not yellow, not pale, not green. Just off). Today he gets to have another colonoscopy and an endoscopy. They don't think the kidney stone went away after it was blasted. They'll also be looking for other sorts of blockage. Ain't that a kick in the pants? I'm hoping that he gets to sleep through it all or be medicated enough to not mind it all so much.
Thanks for your words of comfort. I'll keep soaking them up.
