My father has discharged this afternoon. For some of you who were asking about him, thanks for your concern and he is doing okay now. He will only need to go back for check up next wednesday.
However, it is bit difficult for him to move around and sleep because there is a pack connecting to his urinal tiub. Anyway, it is consider lucky already as it was not problem with the prostate. He used to have high PSA (Prostate specific antigen) but this round the level is low and thus the chance to get prostate cancel is low.
Get well soon Dad, love you!
