Food has for years gotten”stuck” in esophagus. Increasing frequency and severe sub-sterna pain. Contacted Dr. Connor Loftus. Flew immediately to Mayo R. Endoscopy (which I have been avoiding for years). Result: no stricture, no cancer. Given Levsin for occurrence. Happened last night, took 45 minutes to get relief. Next step esophageal magnometry: anybody have any experience with this?
