Doug,
So sorry to hear about your friend! Hope all goes well with him and that you are able to somehow get there to be with him and help out in any way you can.
On the lungs, let's just hang on until we know more. I know it's hard not to jump to conclusions, especially with the way things have been going recently, but until you know more...you just don't really know yet.
You have a enough on your plate (as you indicated), so other than getting tested, try to focus on the other things you need you to. One foot in front of the other (as they say). Just you are "they" anyway. They certainly come up with some good sayings.
Most hospitals will let you fax a signed release giving permission for someone else to pick up your records. You really should have those. They can usually do it via email if you don't have fax capability. You will need a printer and scanner though if you try to do it via email.
I hope you are able to take care of transportation and other needs while your friend recovers. Certainly is not going to be an easy recovery for him!
Hoping for the best on ALL fronts! Hang in there buddy!
Mike
