The symptom is chest pain under my left breast it's not behaving like any of the serious conditions that would come to mind, which is the only reason I managed to sleep last night. But I'd assumed it would be gone when I woke up and it's not, which is making me very anxious. I had a very strong heart palpitation not too long ago. I got up to plug in my phone, sat down and all of a sudden my heart was fluttering so strongly the entire right side of my chest seemed to be shaking (idk why the right side). While I do get palpitations often they've only been this strong once before so it really freaked me out. Now I'm afraid that if I stand up it will happen again, or that something worse will. My mom had to bring me food because I refused to go to the kitchen and I've been looking up hospitals near me, apparently there's one 10 minutes away.
