I'm with selmaS--sounds like reflux----i used to get the chest pain and back pain that went up to my neck and even made my teeth hurt, sometimes---but it never made my arm hurt. However, the pain was bad enough that I totally understand why someone would go to the ER thinking they were having a heart attack.
A GI would be a good idea, but even you family doc could put you on a PPI to see if it would hlep.
Hi and welcome to the GERD forum.
It sounds like this could all be stress related GERD....was this ur first child?
Congratulations, on his birth and I am sorry he is in need of medical intervention.
The stress of a new child and marital stress all can cause reflux....
In addition to meds, u will need to modify ur diet and lifestyle....
I can not counsel u on ur marital issues, but if u could resolve them, u may feel better....
U went to the ER quite a bit, have u tried a GI Dr?
