We are leaving for colorado within 3 weeks. I want to take my sister. She has an aneurysm that has been coiled. She asked the dr if this is ok to do. He says yes. But just travelling up and down the hills in hamilton give her pain. She thinks it will be worse in the moutains. This has been explained to her that the pressure change there is different and she may even be pain free for the 2 weeks. Can anyone find me a web site with this proof? It will make her feel more comfortable about going. She lives in fear.
