Thank you to everyone for happy thoughts. Husband is ok, at least in the heart department. He has a sinus infection, a touch of bronchitis, and a fever, but he's ok. Heart and lungs look pretty good, overall. The doctor wants him to have a stress test to be sure, but blood work, chest x-ray, and EKG came back looking good.
I told him if he ever scares us like that again, I'll kill him myself! And then hugged and kissed him until he told me to quit it :)
Thank you, again, for propping me up while I was quietly freaking out. I love you guys!
