And the hiccup question...Yes, diaphragm irritation is a major cause of hiccups, and some people get them during recovery. They are definitely uncomfortable during early recover. Fortunately they don't last long, and become less frequent as recovery progresses.
I know why you ask about their affect on the wrap, but I've never heard members here mention their doctors having any concerns over their hiccups. They can be painful, but from what I've seen here on the forum, it doesn't seem to be an area of concern for surgeons. It would be a good question to ask, though. If you do, let us know what they say.
