Wow you have been all over the world! How exciting!! Sorry about the avn! I'm glad you have such a positive outlook. I used to be an active person, but I just can't seem to do anything anymore. If it's not pain and swelling, it's the FATIGUE that gets me down. It just seems like it's on thing after another after another. I want to have more good days then BAD ones. I hope that is coming soon!!! I wish I could be active again!
