My wife came home from chemo and mowed our lawn by hand, a pretty big one, I lost her in January to a side effect of her bone marrow transplant, chronic graft versus host, but she reacted differently to meds than the normal person so don't let this discourage you just be aware, my family understands how things happen, we are not bitter, we gave it our best shot and she was very brave, some graft versus host is good but ask them what is being done to prevent chronic graft versus host, something to do with her donor and certain things they do now to prevent it, I would say if you can avoid the bmt that is a good thing, keep that option open if possible, but I am not a doctor so talk to him get his or hers e-mail and communicate and make sure all meds are taken listen to your doctor they have more knowledge than us,good luck my prayers are with you stay strong, don't give in and exercise all you can.
