Earring just fell out!!!!

c

I'm on holiday atm and I was playing with my hair, and my cartilage piercing came out!! I managed to find the earring but I can't find the screw on ball at the front so I just have the back and the wire through my ear atm and it's prodding into my ear. Should i go to the shop and get a new one put in tomorrow? It also hasn't healed Please help I'm only 14 and I'm worried 😩
