Hello, I Am A 24 Year Old Female And I

Hello, I am a 24 year old female and I lifted something heavy above my head a few months ago and heard a weird sound in my body but I pop my joints all the time so I wasn't worried. Then I started experiencing a weird chest pain on my left side and it kind of feels like one of my rib bones is not in the incorrect spot like where it should be attached to that middle bone. Now i am experiencing numbness of my left arm. Should I go to the emergency room? I don't have insurance so I worry about that but my chest hurts when I take a deep breath so now I ask you what to do.
