Should I head to the ER??

Ca

About a week ago I turned over to my side while trying to get some sleep. I felt this ridiculous pain right under my rib cage between/below breasts. I screamed out in pain. I’m thinking I tore my upper an muscle?? I’ve been in pain ever since. I can’t get out of my car, sit at work, stand for long, or even layback for long without pain. Hurts even more when nugget kicks up 🤦🏻‍♀️ Assuming it was just a muscle issue, I haven’t contacted my OB about it. In googling it, I’m noticing it could be signs of something else. I have an appointment this coming Friday. Should I wait to tell her at my appointment? Or should I make a trip to the hospital?
