Hi. Woke Up And Rolled Over On Bed From Left

hi. woke up and rolled over on bed from left to right. My left side pressed against the bed and it felt like my left rib cage stretched back and something got stuck under it. It hurts slightly. It feels like my heart is stuck underneath it. If I apply pressure, move, bend or twist it hurts. If I yawn or take a deep breath it feels like something is pressing against my left rib cage and it hurts. Help please!
