So my anxiety has been off the charts lately. Horrible. The pain is horrendous.

I had a 24 hour Holter and I get my results on 10 business days .___.

The thing is: for the past week I've been waking up real early, 4 or 5 am with a horrible chest and arm pain sensation. The pain in my chest is more towards the left side, either right below my left armpit but right next to my left breast or in my left breast area. I can feel the pain radiating from there to my arm. My left arm usually feels a bit numb, as well as my fingertips. And sometimes like now, it hurts.

I had a panic attack when returning from the Holter and medics measured my BP, sugar level, did an EKG and all normal.

These past days, I've noticed my stomach feels burning and I can tell acid is really strong.

Could the acid reflux be causing this pain or not? Right now I woke up with horrible chest pain but when I take out my oximeter, it is actually in the 70s - 80s. Sorry if I make little sense, I am sleep deprived tbh 

Should I run to the ER?
