For this reason, I recommend taking a PPI omeprazole, pantoprazole, etc. and see if it helps improve your situation. If it does not help, I would recommend going to the ER for a physical exam and some tests:- A chest X-ray study- A cervico-thoracic spine X-ray study- Amylase and lipase plasma levels- LDH plasma levels, CEA plasma levels should discuss with your doctor on the above tests. Hope I have answered your question. Let me know if I can assist you further.
