Is this still consider as Gastritis?

I do experience symptoms like near vomitting which happens to me at the past but rite now its like some sour feeling in my throat which about to come up and i get burping alot.In many cases i do have chest tightness and discomfort with a little bit shortness of breath both before,after the panic attack.Is this still consider as gastritis or other sicknesses?Any help will be greatly appreciated thanks =)
