He has a scar on his chest and the other one is on his stomach, not on the side, so I don't think it's kidney disease.
True that. I just guessed so, because of the symptoms he shows. Like trouble sleeping and tiredness/weakness during the day. I considered a kidney low functioning, not a failure which results in transplantation, but you re right about the scars. It doesn’t explain them
I think he got a kidney disease since childhood. If anyone for any better idea let me know.
