I had a patient once in Emergency with identical symptoms. She was diagnosed with panic attacks after an exhaustive round of tests. We kept in touch, and I was floored by the diagnosis of Panic Attacks. (I'd taken her vitals, seen her physical symptoms first hand, and knew her history-I remeber thinking she is not the panicky type!) I started doing research on panic and anxiety disorder, and came to understand just how physical these attacks really are. I recognized the typical physical changes seen during anxiety attacks (elevated heart, resp, and BP, shaking, dizziness) But did not realize panic attacks could come on without prior anxiety or depression. I failed to appreciate the actual physiological process behind them. They can be triggered not only by stress or anxiety disorders, but by hypoglycemia (when there is a sudden fall in blood sugar levels the brain sends a hormonal signal to the adrenal glands to produce adrenaline) and hormone imbalances and hypertensive attacks.
The feeling of swallowing a large object is surprisingly common in panic attack. It is a spasm, triggered by neurotransmitter fluctuation along with tension in the muscles that create the difficulty swallowing, and the post-spasm inflammation that causes a lump in the throat.
Your Doctor may have considered this possibility but been hesitant to suggest it, or unfortunately, he may have simply ruled out some common possibilities and then taken a passive stance. Symptoms that are subjective in any way, and difficult to measure are often underestimated.
Since you are obviously the best judge of your symptoms, do not allow any passivity from the medical community to discourage seeking an answer. Whatever it's underlying cause, you should not suffer the symptoms and the fear of the unknown.
Hyperthyroidism is another consideration. If thyroid testing has been normal I would still consider a repeat test, ideally around the time of the attack.
If the neurologist did an MRI consider a repeat MRI of head and cervical spine. Stimulation of the nerves due to a disc disorder can trigger an attack of pain, and rush of adrenaline that could produce these symptoms.
There are also certain Autoimmune disorders that could produce similar symptoms.
Consider stepping back and starting over. Start by finding a good internist. After a complete
History/Physical you can determine what testing to pursue. A follow up with a Neurologist, and testing of the thyroid and antibody levels may be a good place to start.
