Oh wow....I'm glad he made it ok through that infection. That infection is wreaking havoc on our schools here in the states right now.
When my husband had an appendectomy, they had complications. He got a high fever, and he was delirious, and I called the clinic and asked if he should come back in. They were so nonchalant about it, and they were vague as to whether to bring him in. Now my dh is 6'2 and 200, and I am only 5'5" so trying to get him back there was tough, but I got him there. He had such a bad infection, they had to reopen him to drain. (ewww, I know, but sorry).
He kept having problems, and we kept insisting something wasn't right. Mind you, he is active duty, and they kept deploying him, even though he kept getting sick. Two years ago, in Japan, he had to be Medivac'd because he got so sick, and they did some MRIs. Turns out, he still had a clamp inside of him.
