Reading all of this seems like déjà Vu or the replay of a movie that I know oh so well.
I really wish you the best and will continue to send prayers. Maybe if I get this heap of mine on the road, I can make a road trip up there for a visit. ( if that's ok with you and your family) it would be nice to see the hospital again and to meet your fighting tiger, Owen.
I actively participate in the LTFU or long term follow up study, but haven't physically been to the hospital since 2011. The study analyses past patients with exploratory treatments and examines how they have progressed since leaving the hospital. They then can see the long term effects of treatment options and help fine tune things for current patients.
Anyway, just know that St. Jude has your back, today and 20 years from now. Owen will always be watched over.
If I can do anything, just let me know.
