Is it normal to have pain caused by the edge of a cast on my arm?

I WOULD CALL MY DOCTOR AND SEE IF I COULD GET AN APPOINTMENT TO SEE HIM OR HER BECAUSE IT SOUNDS TO ME LIKE THE CAST IS ON TOO TIGHT. I WOULD NOT WAIT ANOTHER DAY, CALL NOW, AT FIRST I THOUGHT YOU HAD A PINCHED NERVE UNTIL I READ THE WHOLE THING.
