Utterly Bored.
It will depend on the severity as I have a mate who was a sufferer and an FC. He was limited on where he could go i.e needed to be where there were suitable Hospital facilities. That effectively meant he was limited to the UK,Europe and North America. In these days of expeditionary warfare thanks to Bush & Bliar plc, it could be more of a showstopper. This is one for the Docs mate. Good luck.
