Hi!
I understand the fear that comes with this condition. I want to say though that 4.0 to 4.3 is only .3 of a centimeter . Was your aneurysm measured the same way both times or were they different like a CT scan and an echocardiogram? Echocardiograms usually measure them smaller 4.3 is still considered moderate not severe meaning the odds of it in any year rupturing or dissecting are pretty low. I think you might wanna look this up, but I think it’s less than one percent or around one percent. if you’re having pain though, I would not do the activities which cause it. Try to eat really clean and kerp your your blood pressure and heart rate lower. do a lot of walking that helps with the anxiety and it helps with your cardiovascular system. It won’t hurt your aneurysm but getting stressed can be the worst thing for your aneurysm so just try to be as peaceful as you can. when I was diagnosed with mine, I spent a lot of time in prayer and finally, I was able to give it to God and just do my part to keep everything Under the recommendations .
