Deb,I have never traveled far from home for medical care however I know many people who have. I have a friend that went to Europe for surgery on a bad hip - now that is a long way. If I had to I would make the journey if it meant I would receive better care by traveling.
5-6 hours does not sound that far but I am not the one that is going to have to deal with the distance issue, you are. I would be sure to have a physician near your home town that is knowledgable re post surgical care and if you feel comfortable in making the journey then I think you will be OK.
I hope someone is going to be able to go with you and stay with you through out your time away.
Kindly,
Kitt
