Anxiety?

I fell asleep after a bad high. I have my medical marijuana card. Anyways, I took a nap because I got a little too high, and I woke up kind of high. I was driving to get an iced coffee (I wasn’t high at this point) and it wasn’t until a few minutes ago I noticed my upper back and the center of my chest are sore?? It gets worse or better with different positions and posture. Im wondering if maybe I slept weird or am I actually in danger 🙃 I also work at a gas station so I’m constantly lifting, pushing, pulling etc.
