Back pain after drinking?

Got a little too drunk last night and definitely blacked out. Woke up early this morning and threw up a couple times before popping some ibuprofen and falling back asleep. The last few hours i’ve had this aching pain in my upper back between my shoulders and it intensifies when I breath in deep. It feels good to stretch, but I can’t tell if it’s lung pain or muscle pain. Anyone had this happen to them before? I’ve also been having bad acid reflux today and anxiety as a typical hangover. The last couple days I had a scratchy throat and some congestion like allergies or a cold, so i’m not sure if that’s playing a part in this too, but I’m worried about this back pain. I just took around round of ibuprofen and it hasn’t touched the pain.
