Yes, badly broken, I had an op to pin it all back together. It was several weeks before the swelling in my hand and fingers went down, I couldn't make my thumb touch my fingers for a few weeks. Could not make a fist.
I took pain killers, and got a small physio ball to practice squeezing. When the plaster came off it felt bad, so I had an elastic bandage on at first to still give some support.
You really need to do exercises every day quite a lot , it will gradually get better. You need to force it a bit at first, the physio made me push it, which I was scared to do. YouTube is helpful - see www.youtube.com/watch?v=zHepbNzZRhQT
Now mine is fine, several years on. Keep doing the exercises and if worried, ask to see a physio again.
Changing from a Manual car to an Automatic after driving manual for around 50 yrs
Recalled for a further appointment after a routine mammogram
Good luck.
