Thanks for the tips and advice. Lois, thanks for the welcome and the encouraging words. You?re right about the bumps along the way, sometimes hour to hour makes a huge difference to how he?s feeling and you?ve just got to roll with the punches. Doctorquest - you were right on the money. He had the sympathectomy in the first place to control reflex sympathetic dystrophy on his kneecap following a hamstring release. Interesting he doesn't have POTS but he does have lots of autonomic symptoms such as flushing, excessive sweating, migraine, gastroparesis, J tube, extreme facial nerve pain, dizziness, etc etc but his BP isn't unstable enough to have POTS (so we?re told). Over the last 6 months he has tried really hard to get up for as long as he can tolerate everyday (usually only 20 - 30 mins) but it isn't getting any easier and he isn't feeling any better for doing it. Usually it takes the rest of the day to recover and he's losing motivation. Rob
