Incredibly bad pains in my left side when sleeping on it.

Just wondering if anyone else has/is experiencing this. I'm trying incredibly hard to sleep on my left side but for the past few nights, I wake up on my left side and it feels like something (muscles maybe) are being ripped inside of my belly. And it hurts A LOT when I try to roll over, like I'm putting even more strain on them 😢 is there anything I can do to stop this? :/
