I live with a tightness in the upper part of my esophagus. At times it worsens when I try to swallow food or drink. I thoroughly chew my food and when it's time to swallow I feel a serious constriction as though my esophagus won't open up and allow the food to go down. Once I do swallow, I feel as though the food is stuck in the top of my esophagus. It's very uncomfortable. I then feel the need to belch or burp but can't. I do take large quantities of medications both morning and evening. I have always been able to swallow all the medication at one time with water. I'm wondering if I have scared my esophagus or is something more serious happening?
