Anxiety or Infection?

I have an appointment to see a cardiologist a week from today, but I'm starting to worry about whether I need to make a trip to the ER. Or whether it's my anxiety playing tricks on me.

Quick backstory: I'm 29, have mitral valve prolapse, saw my pcp last week - he did an ekg, came back fine - took blood, my liver/kidneys are fine, he recommended an echo just to be safe. I have that appointment in 7 days.

I've been having a pain in my back and occasionally in my chest. It's been sporadic for a few weeks, but since last night it's been almost constant. I've been having awful palpitations but I know my anxiety/new anxiety meds could be causing that.My oral hygiene hasn't been the best - especially with the acid reflux I've been having for a few months. But that's making me fear it's endocarditis - which of course makes the anxiety and the symptoms worse.

Should I be concerned that it's an emergency? Or should a cardio visit in a week be just fine?

If you are having worsening chest pain, it is probably best to get this checked out.  You are young and coronary disease is unlikely, but not impossible.  Getting a quick evaluation at your local emergency department or from your physician is not unreasonable.  However, that being said, this could all be explained by anxiety so don't get too concerned.  Best of luck.
