Hi Joe,
In response to your questions about skydiving and SCUBA diving, I've been doing both for years and intend on continuing both activities post-op. Sure I'll consult with my doctor before taking part in these activities long after my surgery (4/27/12). And I won't assume the risk if there are any balance issues or pressure concerns. However, I expect to recover from my surgery and hopefully return to being adventurous once my body is ready.
Now, if for some reason I'm unable to perform those activities following surgery, I'll just press on and find other adventurous activities. There are plenty of fun activities you can do that don't involve altitude or pressure changes. Rock climbing is fun and relatively safe since you're on a rope. Riding quads is a blast if your balance is okay. There are endless opportunities out there.
For your trip to Malaysia, maybe you should check into parasailing or jet skiing. You could also enjoy SNUBA, which is like SCUBA without the tanks. You breathe from an air hose on the surface without having to dive deep. It's much safer and you still get to see all the things you would on a normal dive. Plan fun activities that are safe. That way you won't be disappointed if you get the thumbs down from your doc regarding not so safe activities.
Joe, what I'm saying here is that I'm not planning on letting my AN control what I can and can't do. Sure it may play a factor in some activities, but I'll just have to find other fun things to do then. Have a fun trip!
Dave
