Consult a Gastroenterologist (Gastro Specialist): Yes, you absolutely need to see a specialist immediately. A General Physician's Gaviscon syrup is only a temporary fix for the burning, not the obstruction. ​Upper GI Endoscopy: This is the gold standard test to look inside your food pipe and see exactly what is causing the 'obstruction.' ​Cardiology Review: Since your last Echo was 6 months ago, you need a fresh review with your Cardiologist to monitor the 47mm aortic dilation. An increase in size can sometimes correlate with new chest symptoms. ​Barium Swallow: In some cases, a specialized X-ray (Barium Swallow) can help visualize the path of food and any external pressure points.
