Hi Kelly,
I felt compelled to respond to your post. I also was recently dx with MDS in August '07 after two years of abnormal blood work and finally a bone marrow biopsy. I'm 41!
I have RARS and also have two siblings that have not been tested ( or told of my condition) as possible donors. I'm still dealing with the shock & haven't had the courage to tell anyone. My wife is the only one who knows at this point. My health history was unremarkable until the abnormal blood work surfaced. I'm very healthy and an avid distance runner. I have a consult with Dr. Doug Smith at Hopkins the end of December. My Hematologist highly recommended him. I'll let you know how it goes.
All the best,
Tom
