I absolutely agree with kmailloux. When found my aneurysm was a 4. I was told when it reached 5 we would discuss options. I ended up with an emergency dissection at 4.5 cm. Emergency everything just like kmailloux said. Be mindful, don't lift anything that causes you to grunt, moan, groan, hold your breath, or strain. ASK FOR HELP! I am a 71 YO female and this happened to me at 68. I am going in for another surgery for correction in February. I had no symptoms then and have none now.
Best wishes
