I'mmmmm back.
After my successful exit yesterday as an emergency hospital heart patient, and after several tests and X-rays etc, it is now a case of the cough and whatever I have been suffering with has been determined as influenza.
I was set up nicely in a private room in ICU all wired up with the heart monitor beeping away.
Then late today was told pack your bags and home you go.
The surgery is postponed for another week until then "flu is cleared from your system.
Came away with some potent anti-biotics that will hopefully do the job, and the thrice postponed surgery can then go ahead.
