I too had such severe chest pain it caused me to double over, and eventually started radiating down my back and jaw. I had short Barretts esophagus, and was on 40 mgs. of nexium a day. I, didn't know if it was my esophagus or my heart. I went to see Dr. Smith an esophogeal specialist at Temple University, in Philadelhia and Dr. Meshkov, a cardiologist at Temple. I had a heart catherization which showed a 60 percent blockage in the distal artery; I did not get a stent, but was put on 40 miligrams of lipitor. Dr. Smith the esophogeal specialist ordered a esophogeal motility test and a barium esophogeal test. These test showed I had a weak esophagus, and the sphincter was not closing. A weak esophagus can not take a large amount of heavy food, hamburgers, large plates of potatoes, etc. It will cause pressure on the esophagus and severe pain. In addition to the nexium. Dr. Smith put me on carafate suspension for six weeks. Though I had a heart blockage, the pain was coming from the large amounts of food I ate during the day. A week esophagus can not take the pressure of a normal esophagus. You need to see both an esohogeal specialist and a cardiologist. Since I changed my diet, and take my medications faithfully, I no longer have chest pain. Please take action immediately. You don't need to live with this pain. Good luck. Betty 899View Thread
