trojangal,
does coumadin make your husband really weak? It made my boyfriends Dad super duper tired after he had his heart attack. I am sure he won't have to stay on it forever. I think it is a blood thinner? Tell him to be careful not to cut himself b/c when my boyfriend's Dad accidentally pricked himself (not sure how he did it) it took awhile for his blood to clot. Like 2 hours long!
I am sorry to hear about your hubby. I'll be thinking about you. I know what you are going through! It's tough, but you are working with the best doctors in the nation.
My thoughts and prayers are coming your way!
