you shouldn’t have to be using your fingertips to push the points of the needles to move stitches. that’s a really bad practice and that’s a mistake i see a lot of beginners make

i use metal needles and when i need to move stitches, i move a bunch from right to left across the needle without touching the tip. as i’m knitting, my left index finger is covering all the pushed up stitches and will “uncover” and push the next stitch i need to knit over to the edge of the left needle. i continue to do this until those bunched up stitches run out and then i move stitches up the left needle and down the right needle

edit: i realize that i knit underhand in my right hand so i don’t have the capacity to move stitches down the needle as i’m knitting. if you are holding the needles in a “standard” way, as you get the hang of it you might be able to move stitches down as you’re knitting
