For about 6 months, I frequently experience a fairly localized, left sided chest pain while swallowing carbonated beverages, especially when they are cold.  Feels sort of \"mid-chest\", very brief (1-2 seconds), sharp in quality.  Had a similar issue many years ago, but this has been more persistent (though only with swallowing carbonated beverages as above).  GERD?
Thanks for your question on Chat Doctor. I can understand your concern. Yes, possibility of HERD (gastroesophageal reflux disease) is more in your case. Your symptoms are associated with eating specific food. So HERD is more likely. HERD is due to laxity of gastroesophageal sphincter. Because of this the acid of the stomach tends to come up in the esophagus and cause symptoms of mid-chest pain. So follow these steps for better symptomatic relief. 1. Avoid carbonated Chat Doctor.  2. Avoid hot and spicy food. Avoid junk food. 3. Avoid stress and tension, be relaxed and calm. 4. Take pantoprazole tablet on empty stomach. 5. Quit smoking and Alcohol if you have these habits. Don't worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
