I appreciate this thread. I am having the sensation of a lump in my throat, and before I started reading your posts I was imagining the worst. Sometimes I have a discomfort in my esophagus that's farther down, behind my breastbone, but usually it's just below where my adam's apple would be.
I also have digestive problems (food allergies, irritable bowel and acid reflux), a neck injury, and TMJ (jaw problems) that affects tension in my neck. It really feels to me like it's *all* involved in the lump feeling.
I have a harder time swallowing liquids than solids, and I sometimes have a feeling that things I swallow are stuck or are being pushed back up by pressure from organs below.
More specifics: Dietary triggers are spicy food, meals that are too large, or food that makes me phlegmy. Another one is carrying heavy bags on one shoulder for too long, which throws my neck out. At one point I had pain from swallowing that radiated to a specific spot behind my right shoulder blade. My chiropractor adjusted my ribs and it went away.
I do feel like anxiety is a factory, like the article said -- even when it's not the primary cause. I'm so glad I found this site. I will make a doctor's appointment, and a massage appointment, but meanwhile I will not worry that I am dying.
