Thank you for posting your question here, I will try to answer it to the best of my abilities.
It is possible that you have developed a gastro esophageal reflux and that is what is causing your other symptoms. I recommend you see a doctor and have him run a couple of tests on you ( ph monitoring or an endoscopy
From these tests the diagnosis can be confirmed and once that is done he can start treating you by prescribing you with H2 antagonists, antacids and proton pump
I hope this answered your question.
