I'm late to the thread. Hopefully this issue is resolved by now, but the distended stomach is possibly a side effect of the pain medications. My father-in-law had a bad fall off a ladder several years ago and experienced the same distended belly. Once they reduced the pain medications it resolved pretty quickly. The docs he was seeing weren't sharp enough to know the drug side effects. I believe it's called narcotic bowel syndrome. His physicians were at a loss, but when I described the situation to a physician friend of mine, I didn't even get to finish the sentence before he cut me off and explained everything. He said it's pretty common among older males. I am not a physician.
Also, if you think they need more gift cards, I'd be happy to chip in for a second round.
