Vitamin b12 injection needed asap

[Somethingsosimple]

Advice please. Grandmother of 96 needs a vitamin b12 injection. She was promised by district on Wednesday. They haven’t been and now can’t come until next Tuesday. She is overdue as she has been in hospital for major surgery. GP surgery too busy for another week. Where can I get it done? We have the b12 injection just need someone to inject it.

Could you ring 111 as I know they pass things to district nurses? Or phone the gp and explain it needs to be done ASAP and if you get nowhere, contact pals?

Do it yourself? There's a video you can watch that shows how to. It's really not difficult.
