I have arm pain for 2-3 days now.. it sometimes hurt when I rest :(
I unintentional loss weight 5 months now...
Chest pain and feels like food is stuck when I didn't swallow anything
And past 2 days I wake up and have stomachache and "poop"
I also burp even though I didn't eat anything
And today I ate coffee macarons and I had chest pain.
GERD, ANGINA, both or something else?
I'm going to the doctor in few days...

Only the Dr can diagnosis angina since it would be hard to separate the symptoms from the GERD. For the GERD there are a lot of nutritious things you can eat that can help stabilize it a good bit.
