smacked my funny bone a few days ago and my arm still hurts

(22F, 130lbs, 5'3")

i hit my funny bone REAL hard 3 times in a row over 2 days, and now I get a sharp shooting pain in my elbow whenever I lift/push anything. it was a constant pain yesterday (the hits were 2-4 days ago), today it's been on and off, but when it's "on" it's worse than it was yesterday

should I be worried about this? or will it fade on its own? TIA!
