Yes, gas pain can cause the discomfort you describe. Of course, you want to ensure that the heart is ok first - a stress exercise test can be considered for this.
If the heart is ok, you may want to consider evaluation for dyspepsia (either an ulcer, inflammation or GERD), which may cause the symptoms you describe. An upper GI series or upper endoscopy (which is the more thorough test) can be considered for further evaluation.
A GI referral can be considered for further workup.
Followup with your personal physician is essential.

drinking ice cold water helps too.
By the way, when chest pain occurs, I take very hot water which helps me in burping. As soon as I burp, I get relief. Also, after a meal, especially after dinner, go for a long walk and leave atleast 2-3 hours gap after your dinner before you go to bed.
