Here is the update from my mom's email.
Thank you all for your prayers on Andy’s condition. I’m happy to say that he’s doing really well and we give thanks to the Lord for this improvement. He has just come back from an echocardiogram and a stress test. The echo results were read as normal, but there is a question about the stress test results so they will be doing a nuclear isotope scan/stress test tomorrow to rule out any heart-related issues. This test is more precise with a 90% sensitivity. At this point, his doctor is fairly certain that it is pleurisy…and from what I’m learning, this condition actually mimics the symptoms of a heart attack…which explains the painful deep breaths and pain radiating into his neck and shoulder. It can occur after a viral infection such as influenza (which he had two weeks ago). If the test results come back with good results, hopefully he will be released tomorrow (Sunday). Again, we are so thankful for your prayers.
Give thanks unto the Lord for He is good!Psalm 105
