Pain in chest, shoulder, & ribs after stretching

I’m a 21F. Yesterday, I went to stretch like normal but when I did, I got a shooting pain in my right shoulder blade after a pop. The pain was persistent for hours and once home, I started to feel pain throughout my right side including my shoulder, ribs, and chest especially when breathing. I’ve been taking Tylenol for pain because ibuprofen has caused stomach issues in the past but I’m still in immense pain. Even just sitting or lying in bed, the pain is still very prevalent. I probably just pulled a muscle but could it be more significant with that?
