my brother has a new health problem

So when my brother came over on Friday, he told us that his doctor had a lot of trouble finding a pulse on his foot.

Now, none of the reasons this could have happened are good news, but some are obviously worse than others, and I'm going to admit I'm worried.

So I'm taking all hugs and prayers anybody wants to send my way, and if you would include my brother in those care packages, that would be awesome.
