Anyone know what is a pain in my lower esophagus near my sternum?

Should be evaluated. This could be a number of things. It could be something as simple as acid reflux (or gerd), but can be other things that are more serious. This includes some neoplastic issues and it should be checked by a GI doc, espcially if you are having pain swallowing. Also be cautious as any form of chest pain can be cardiac in nature and this should be something else you should discuss with your primary.
