Hi thanks for your question.
You are having aortic aneurysm
There is nothing to worry as your going to have a consultation with CVTS surgeon very soon who may suggest you operation.
The danger associated with aneurysm is they can rupture anytime leading to fatal bleeding .
I would suggest you to remain relaxed as tension would increase blood pressure.
Increase in blood pressure can lead to rupture the aneurysm.
Hope this answers your question.
