Can ice cure my "ulna" bone on my left arm?

Usually when i curl a barbell or dumbell, my left ulna bone really starts to hurt, i kinda nervous to do more of these because im scarred that it might break and i was thinking maybe i need more calcium and vitamin D, (but please if i need those vitamins though) but then i was thinking of using an ice pack for my arm, so will ice help or will vitamins will?
