Wherethejourneytakesme, thanks for your comment, and what you say makes a lot of sense, mum is not very mobile at all. The problem is actually getting mum to drink and eat - despite us, and doctors and the paramedics, telling her she must at least drink, if not eat, she often doesn't. She says she just doesn't feel hungry, or even thirsty, much anymore and often feels so sick she doesn't want to anyway. There's also the problem of her low mood - she's so tired of feeling ill that she doesn't really see the point of doing what she's supposed to. She is on antidepressants, has been for a long time, but they're clearly not working much anymore.
Sis took her to the GP today. Her GP admitted that, seeing as all mum's tests have come back normal, they really don't know what's wrong with her, although agreed it's clear there is something going on. The GP had a look at all mum's medications - it appears she's on about 15 different meds, plus 2 inhalers and a steroid skin cream. And, worryingly, she hasn't had a review of her medications in a very long time (we have an annual med review at our surgery!).
So the GP decided to take Mum off of some of her meds to see what effect that will have - 7 in total. She said for a start, mum doesn't need to be taking 2 meds for high BP - her BP has actually been very low, sometimes dangerously so, recently. Honestly, I sometimes wonder exactly what the doctors at mum's practice do - not a lot, it seems, and I really think, as does mum, that her doctors had more or less written her off because of her age. Sis did some straight talking with the doc and it seems to have shaken her up, hence the doc's change to being proactive. She's also taken mum off 2 or 3 other meds that have known gastro side effects, plus a couple of others, I can't remember what. Mum is to go back next week for blood tests, and then see the GP again a couple of days later. So at least, finally, something positive is being done. The GP said in the meantime, if we're at all worried about mum, to ring for the paramedics again.
I think part of the problem is where mum and sis live - on the edge of a large town, in a heavily populated area, and the GP surgery is swamped. Whereas we live in a rural area with a much lower population and have no problems at all with our doctors.
I'm busy tomorrow, but am going to have a weekend of doing nothing - I'm so tired my body feels like it's shutting down. I might even stay in bed. Got a busy week next week, so I need to build up my reserves. I also have a cold sore on my lip, for only the second time in my entire life, I guess because I'm run down.
