Yeh I know. I can just see it happening one day. A week before I've got a holiday planned and he ends up in hospital.
As I've found out in the past, its not that difficult to get yourself into hospital when you really want to. It seems doctors err on the side of caution most of the time. (One of the reasons why I knew, a few months ago there was nothing wroing with him when GP refused to come out, paramedic refuses to take him to hospital, hospital sent him home).
To be honest, I'm not going to know it if its serious or not. In the past, hes gone from thinking hes dying one day, toi saying he feels better the next day, then ill next day.
