@aine Each situation is different. I think for my husband, post-transplant was easy. He stayed home for a couple of weeks but my recovery was very quick so I was doing pretty much everything, always be conscious of protecting the incision, very soon. As soon as I got the "go ahead" I was back at my health club using the gym and pool.
I hope your sister recovers post-transplant as well and as quickly as I did.
