Here's an update on my son Michael. He had an Echo-cardiogram & ultra sound of the chest. He still has the pressure on his chest, but Thank God there were no blockages. They did find a leaky valve on the left side of the heart. He has had a murmur since childhood, so that could be part of the problem. I also think some of it is stress, I guess we'll just have to wait and see. At least it not an emergency and is fixable even though it will probably mean surgery. I wish he was up here, but that's not going to happen so I just keep praying. Thanks to all of you. Arlene
