it's clear you have done your research like most of us here. It's standard not to operate on the smaller aneurysms and many of us are in the wait and monitor mode. I certainly understand the frustration this brings. My doctor told me only to not lift heavy things. Not sure what that really means. I still lift 40lb bags of dog food at the store to bring home. I have had mine for at least 2 years now with no additional growth. Since they seem to have no idea what the root cause of them are I personally think that they are just playing it safe by stating "take it easy". I headed for 60 years old, I'm overweight and I'm kind of OK with all of it. So my advice is do what you think is best for you and your family and your particular situation. There is no right answer only the one that you decide is best for you. Maybe a workout with lighter weights. One more observation. We all get scared when we get the diagnosis and ponder the results of it rupturing. However in this group I have not heard of anyone having that happen. There can be many reasons for that. Modified behaviors or if there was a bad outcome it doesn't get reported back. I appreciate the dr.s giving me worst case scenarios but i think those happen very rarely. Again maybe it's just my outlook and my situation. Hope this helps.
