I’m 17 F with no prior heart conditions, I went to the ER a couple of months back for a completely unrelated reason (acid reflux) and went through a whole run through (X-ray and everything) and everything came back alright. 

Went to personal doctor last week after hyperventilating and she said everything seemed to be fine and that i was just anxiety. 

However, I have these intense heart drop feelings to the point of extreme discomfort, not really unbearably painful or anything but they last about four to six hours straight. 

Just heart drop after heart drop repeatedly until the point where my ribcage and and my left side hurts, again not unbearable just painful and quite anxiety inducing. I can still breath pretty normally and take deep breaths without any pain. 

I get back pain too but I’m not sure what is caused by heart drops and what is caused by the very shitty posture. I was thinking it might be due to my tenseness as well as I tend to get very stiff jaw and body due to my anxiety.

Does anyone else get intense long lasting pain like this or should I go back to the doctor’s?
