My husband has this and the DR says he can go back to work even if he can't walk around the block without getting shaky and can hardly breathe. There is no way he can work. I can empathize with you - we are in same boat. Our family DR knows he can't work - the other DR was a Heart Specialist. So here are two DR's (yours and his) that say you both can work. Maybe another DR would say differently, if you'd like to try another. As my husband's wife I know he can't work. He is getting disability and it will be cut off if the DR reports to our insurance co. that he can work. I wish you "Good Luck"
