Thanks for the advice Jim. Unfortunatly I have no other option to fly after my treatment unless I want to spend my summer in Germany...also flying is my biggest fear which gets me all uncomfortable which wont be good...

Does your wife also have RSD in her feet? Its strange because I also get colour change in my left foot but dont have the RSD pain there, similar less pain however which is only triggered from over stressing it.

Im really dying to get back to my life as I have passed through a very bad time and am still going on. The doctor did say that if the treatment works he told me to take it easy for 6 months to 1 year. Although difficuly, that wont be a problem. Another concern I have is that I must start rehabilitation on my knee, mainly increase muscle strength and mass but not sure when to start? Best to take it 1 step at a time I guess...
