i dont think its any physical problem, i know for sure its weakness as he is 4 kilos under weight now. we are trying to get his weight up lets see .
He sits on the bed wen the back portion os the bed is made slant.
but sitting on chair is issue as after a few minutes he feels drousy.
i will check his status today cause yesterday was the first day when he sat for long time and walked 3 times ...
totally he has lost 12 kilos, but just after radiation got over he was 57kg which is normal ... but this one month hospitalisation with all issues has made him loose 7 kgs ...
We need to get him to atleast 54 now.

Also i changed the dates in signature
