Hi Rick, as soon as they found my aneurysm they put me in hospital but it took over a week to decide the best way to operate, either coiling or clipping because of where it was located. I was glad it was coiling as it was just a little nick in my groin! Besides a bit of a headache afterwards it was virtually pain free. I stayed in intensive care for one night and then went on the ward for another two weeks. Mine was 7 mm. I went back for a scan at six months and everything was fine and my life is completely normal. I don't suffer from headaches or anything and I feel really lucky that they found it and repaired it. I am due to go for another scan around christmas time and I think they will just keep an eye on it to make sure everything is as it should be. I know it is scary but the sooner it is done the sooner it is over. I hope you know soon enough when you are going. Keep smiling :-)
