I know how you feel, man! Between osteoarthritis and my cardiac problems, I haven't been able to do jack for several years. I would give a lot to be able to go to concerts, go fishing, walk my dog for a distance longer than 100-200 yds! It gets really boring doing nothing much. I'm hoping that they get this heart problem figured out.....I can deal with the arthritis pain......Hang in there.....sounds like you've got a reasonable chance of regaining at least some of your physical activity. Pulling for you!!
