Pinkie finger on left hand

I love knitting!
However because I knit the UK way since the 1950’s , I notice my left little finger is always bent when I knit
Is there a new way I can knit to stop this little finger hurting ?
I think the Americans call the way I knit
Thank you

Have you tried holding the yarn in the right hand? There’s a way of flicking the yarn rather than throwing it around the needle. There’s also Portuguese knitting.
It might help to look at various videos online to see the way different knitters hold the yarn.
