Dear friend, welcome to HCM.
little relief with treatment may mean inadequate / wrong treatment/ diagnosis. there many forms of acidity problems. you need an endoscopy
(OGD scopy )to look for any serious threat like an ulcer/ gasstritis etc/
pl. see a gastroenterologist who would guide on that.
can take tab. Pan-D or alike 1-2 times a day till then , get ecaluated in detail. a good doctor can always treat you well. liq. gelusil-MPS
2 tsf three times a day.
it is curable. do not worry.
else post me details of all tests done and detailed symptoms.do you get sour eructations, does it get worse in sleeping position, on empty/ or full stomach?
take care and keep me posted on your progress.
