OK, I've persuaded her docs to do a home visit now but still a bit edgy and just need to let it out somewhere!
MIL is 74 and has COPD (roughly chronic bronchitis). About 1pm today I get a message from dh, who stayed with her last night, that she has pain in her back and breathing problems (he's now at work, miles away from her and home). I think 'WTF, why haven't you called a doctor?' and call MIL. MIL can hold a conversation, which was a bit of a relief, but I was still worried. Called her GP surgery - of course it's lunchtime so no-one around and receptionist says call back at 2.30. I'm not entirely happy about this not least because the later you leave it, the less likely you are to get a home visit and I want her to be seen today. (She hasn't driven for years and doc is in nearest town - MIL usually gets a lift for planned appointments.)
Spoke to my sister, who is a nurse, who confirms that she does need to be seen today. Call back the surgery and push, they go round the houses but eventually agree the duty doc will go out. Although obviously no idea when as duty doc doing all urgent requests and home visits.
Phew. Am a bit happier now. But still worried. And a bit alarmed that even though I told the receptionist when I first called her that MIL is 74 and has COPD etc. etc. etc. she still didn't put me through to the duty doc or get him to call back. It was only when I had double-checked I was right and felt able to push that we got it sorted.
