I went through years of testing for the difficulty in swallowing, lump in throat and sometimes couldn't even swallow my own saliva. It was extremely painful and would cause pain and pressure up mt neck, into my head, in my chest and down my left arm. Even thought it was a heart attack at one point. Nitroglycerin actually stopped it. Dr. Gave me a script for that but I discovered on my own that it was red dye #40. That dye is in just about everything! If at any time I unknowingly consume that dye and experience symptoms, I start myself on a regimen of 1tbsp apple cider vinegar to 8 Oz water. I just sip some. No need to drink it all. Most of the time it will go away immediately but I'll continue twice a day for a couple of days, then once a day for a couple more days. It may not help all of you but could be the issue for some.
