Hi. I Was Rubbing My Ear And Heard A Crack.

Hi. I was rubbing my ear and heard a crack. I didn't think much of it, but later my tragus started to hurt. I can't touch it without it hurting and I initially hurt it 4 days ago. I was wondering if it will heal itself. I've been told by friends that it'll heal since it's so small, but I just wanted to be sure.
