Hello, I am new here and from Japan, wish my country had site like this. I started to have lung problem as part of complication called GVHD which is from my stem cell transplant from blood cancer, i have other several complications but this is the hardest one. I was in the hospital for three weeks in October and my doctor advised me to take oxygen back home. i use it sometimes when i feel short of breathe or go out walk long distance like visiting hospital but I have not given much information about my lung problem. I also feel sad sometimes but i am not getting much help about it , either. Anyway, i try to stay positive and I thought in this site I could chat with people and share thought and informations. Thank you for reading.
