My mam seems to be locked in a world of her own. Pacing, pacing, pacing, looking at the floor, one arm trembling, by her side, the other curled up into a claw. Hardly interacting any more. She won't speak at all on a morning. The afternoons are a little better, but she paces all day long, from getting up to going to bed. A dramatic change after tea, and then she won't stop talking - mainly questions, over and over, lots of nonsense. I asked her today if her hand or arm were hurting her, she had it curled right up, but she said no. But did she even understand what I meant? Is it worth giving her pain killers regularly just in case? This is utterly heartbreaking.
