This is Dr. David
I am sorry you are having these chest pains and palpitations.
I am glad you went to the ER already.
yes, I think you should see a GI doctor and get an upper endoscopy to check for esophageal wall spasms which could cause your symptoms.
and also a holter monitor test and more testing of your heart by a cardiologist.
also you could be having panic attacks or anxiety attacks as well which can cause chest pain, heart palpitations, back pain.
do you have symptoms of excessive anxiety or panic?
there are medications which can help with esophgael spasms if that is what is found.
