Should I head to the ER again?

Been dealing with severe upper stomach pain, nausea, fullness, constant burping, chest tightness, throat tightness and I can’t keep any food down.

Got diagnosed with gastritis via endoscopy about a week ago after spending 2 days at the ER. I feel like it’s just getting worst tho, even with the PPI and sulcrafate they gave me.

Should I head back to the ER or keep giving the meds a chance?
