Hello doctor , I am having problems with constant chest pain ( chest heaviness) for over 6 months now all ecg eco stress test chest x ray normal. Have a history of acid reflux so constant bad taste in mouth heartburn is there but is relived when on PPI . Recently since past 1 week I am having trouble swallowing no pain but sometimes it feels food is stuck in my mouth. 2 weeks ago had viral bronchitis and had blood in sputum just a tint of blood but it stopped within a week . Also problems with indigestion been diagnosed with ibs also my stomach feels bloated all the time. No weight loss .Could this be any form of malignancies like esophagus cancer or any form of cancer or this is just my anxiety.
