Debbie, it is possible that your problem is caused by a double whammy...
neuro and GI.

Some people have reflux without knowing it, a "Silent Reflux" per my PA.
Nerve damage, short-circuiting nerves, keep one from feeling the acid reflux, but doesn't keep the reflux from damaging the esophagus causing choking and difficult swallowing by narrowing it. Combine that with spasms and it's awful.

You really should get this checked, even knowing that most if not all is neuro.
You might be accruing unknown damage that could be quite serious if left unchecked..ulcerations and even cancer.

I am not saying to ignore the neurological aspects of the problem, but to know that they can cause a GI component as well.

From another who is sometmes afraid to eat when alone,
