I wasn't able to go see him today, but hubby and mil both say he is looking a lot better. They think it is blahblahblah or blablurgblah, ie 2 big long names tha fil couldn't remember.
He has fluid on the lungs again as we'll, and possibly an infection there as well. Lucky he had one of his coughing fits that he gets so regularly last night. The nurse heard it and sent straight for the doctor so he too could hear it. He is now on antibiotics for that too. Hopefully that clears it, but this now the 5th lot he has had since the op, so I'm not hopeful.
More scans and test planned for tomorrow. Mil has gone home tonight. I'm picking he will come back for Wednesday night if he is still in as she doesn't work on Thursdays.
Thanks everyone for the vibes.
