On Xmas Day, Mum was walking back from my sister's house, with my sister and husband, when she fell. My sister said it was like her legs had just given way on her. They then spent from 6pm until 3am with Mum in A and E. Upshot was that she'd broken her hip/femur, right at the hip joint. She had an operation, partial hip replacement. Then the hospital cancelled visiting due to the number of covid cases escalating. Eventually she came out, but they've confirmed that she has short term memory loss. She also has hearing loss, and has been referred to audiology, but she is unaware of that yet.
Coupled with that, she seems to be losing lots of weight. When I eventually get hold of her on the phone, she struggles to keep focussed, and breaks calls off without reason other than she's just thought of something and must do it before she forgets.
I don't have the best relationship with mum, but the changes in her health are distressing.
