Thank you for all the supportive comments and emails, they do help a lot. It's been a worrying few days.
My mother was asked by the doctors to decide whether she wanted to be resuscitated if (they made it sound like when) her heart stops. She does have heart trouble, which has worsened since she's been in hospital, her red blood count had dropped significantly and, for unknown reasons, they weren't even treating it, hinting that her heart problems outweighed everything else. However, after my sis and their church minister talked with mum and the doctors, it seems that the DNR question was simply a routine one they ask every elderly person and Mum isn't in immediate danger of dropping dead. They're also now going to treat her low red blood count, they're giving her a large iron injection today apparently. And they're back to saying she can hopefully go home soon, whereas the past couple of days they've been giving the impression she wouldn't be leaving hospital. I really don't know what's been going on there, sounds a bit like they'd given up on her (unless my sister just got the wrong end of the stick), it's difficult to know exactly when we're so far away.
Husband has been very unwell again the past few days, had another emergency GP appointment on Monday, she said she'd rather not give him anything until he'd had the hospital tests (which were this morning), she felt it was better to wait until we knew exactly what we were dealing with. She did say he could take anti-inflammatories for the pain, but as they interfere with a couple of his heart meds, he'd have to temporarily stop taking them (a worry in itself) until he'd been to the hospital. The anti-inflammatories didn't help anyway.
He had an ultrasound scan of his bladder, bowel, kidneys and prostate first, followed by a cystoscopy and rectal examination (I left the room for those!). He doesn't have prostate - or any other - cancer, which is a huge relief. However, he does have a very enlarged prostate which is severely squashing his bladder and urethra, preventing his bladder from emptying completely. The leftover wee is stagnating and breeding bacteria, hence the repeated infections. The huge prostate is squashing his urethra so much that the wee has trouble squeezing out, which is why it's so painful (sorry for the graphic descriptions!). He's been prescribed two more meds, one to hopefully shrink the prostate (it doesn't always work successfully though), the other to relax the neck of his bladder to allow the urine to come out easier. Fingers crossed they work. He was told he'd be in some discomfort and probably peeing blood again following the procedure (he is! the groans coming from the bathroom sound like he's being murdered) but that should wear off in a couple of days.
Whilst we were waiting to be seen, a young couple came in for a pregnancy scan....the girl was I'd say about 6 or 7 months pregnant and was carrying a pregnancy pack. They were extremely young, she looked to be 16 or 17, the boy even younger, 14 or 15 I reckon. They sat there playing on their phones, the girl draped her legs over the arm of the chair with her feet on the neighbouring chair. She occasionally spoke to the boy showing him things on her phone, he just grunted and never even looked up. Shortly afterwards another pregnant girl came in, around the same age as the first girl and about as far gone, she was with a much older man, her father I guess. She was a right drama queen, pulling faces, theatrically heaving big sighs and giving loud groans, fidgeting and rubbing her back and stomach, even pulling her top right up, exposing her entire belly and stroking it, whilst giving surreptitious glances around to see if everyone was watching her. The thing that struck me about both of these children (for that's what they were!) was how totally immature they were and certainly far too young and silly to even be thinking about bringing a child into the world. OMG don't I sound old!!
I've asked the sleep clinic for a temporary break for a couple of weeks - there's been (and still is) so much going on that my sleep patterns are all up the creek again and there's no way I can stick to their programme right now, it's just too much pressure.
