@Majic, hugs, hugs, hugs, gentle hugs. Sounds like you are really having a time of it. I hope that they've found a combination of drugs that will deal with that nasty infection. The trauma of having had major surgery has stressed out your immune system, leaving it weaker than usual and less likely to fight off the infection. And if you are like me, the antibiotics may start having their own little party in your tummy. Poor girl. I find it useful to take something with probiotics about now -- yogurt with live cultures, raw sauerkraut, even pro-biotic pills (get the ones which require refrigeration, if you can). And let me know how you're feeling.
A body pillow is a pillow which is really, really long -- 3 feet, maybe. I don't know if they are available in the UK. Here's a link to one of many US retailers.
https://www.bedbathandbeyond.com/store/product/bodymate-reg-body-pillow/1011667104 I purchased one before the surgery because I wanted to have something which would prevent me from rolling over in my sleep. I'm a natural side sleeper, and I knew it was best to sleep on my back with my leg elevated -- ice packs in place! -- rather than rolling over and curling up like I usually do.
@Slainte gave me the suggestion of using the body pillow to construct my "elevation station." I tuck one end of it under a large regular pillow, and flip the rest of it forward so that it comes across the top of the regular pillow and comes down to touch the sheet -- creating a split-level pillow platform. When I needed extra height, I placed a large, folded up bath towel underneath the regular pillow to give me another 4-6 inches.
@Pescara, truth is: everytime I log on here, I get caught up in catching up on everyone else's threads (including yours!), and in keeping the games room active, so I run out of time to update my own. I'll post a little about myself in a bit. But first, the games room is calling.
