Hopefully I can help you live more of a normal life than I have 🙂 My aneurysm was 4.5 over 12 years ago. It has been very stressful living with this condition and monitoring every 6 months or so. As it turns out, mine has been relatively stable and is now 4.8. I’m still have very high anxiety with it because that’s my nature. But my doctors/surgeon (primary, secondary and 3rd consultant) say I’m stable and I shouldn’t worry until they worry. But, for over the years I have been crazy thinking about this and didn’t live my life as I would have liked. At 4.3 my advise is, try and live your life…that’s very hard…but you have to try. Keep your BP under control and reduce stress. Yours is soooo small, with monitoring and control, you may never have to do anything. And, if you do, technology will continue to improve and advance that your risk will be significantly lower than it may be today. I absolutely know how you feel and I’ll pray for us both. Happy Holidays!
