Welcome to HCM
We understand your concerns
I went through your description. The symptoms you are having are of typical acid reflux
and you have nothing to worry about complications and other diseases related to this. But should take treatment for the shown results. I hope you are under treatment for acid reflux. If not please do it soon
Having garlic with breakfast often relieves acid reflux. You should try it.
Hope this clears some of your doubts. Available for further clarifications.
