Seemingly healthy son in law has blood clots both lungs

[Byrd]

Sending lots of mojo!  I have a friend who was recently hospitalized with the same thing (hers had gotten so bad that she also had fluid around the heart.)  She's out now and in rehab, so I hope your SIL is quickly back to his old routines.

You're a good dad for fussing over them.  :)
