Yes, your neurologist can request the swallow test first since it is possibly tied to neurology and then, depending on the results, get referred to the gastroenterologist. Do this if it can expedite getting you tested sooner. If your neurologist requests the test, your insurance will be checked, you can call to get scheduled asap, get the test test done, follow up with your neurologist to review results and get next steps.

I also believe your swallowing issue (like mine) is tied to your cervical spine injury/radiculopathies and neuropathies. Cervical spine/spinal cord issues can affect your brain, spinal cord, nerve roots, upper/lower limbs and autonomic nervous system (sympathetic and parasympathetic).

I am happy to share everything I have learned with you. My journey has been long (since 2011) and if I can help you expedite getting to the right doctors to diagnose/treat you, I would love to❣️ I feel like I wasted a lot of time trying to put the puzzle pieces of a very long list of symptoms together on my own. Many doctors look narrowly rather than holistically at their patients. We are one person with many systems that need to work well together. I think this is why there is so much waste I. The healthcare systems and poor patient outcomes. Doctors need to treat the whole person and seek to get to root cause or prevention rather than quickly prescribe medication and send you away due to time constraints. We can end up on a lot of expensive and harmful medications that are only masking/band-aiding problems rather than treating them. Many doctors do not take you off medications once you are on them so you really need to question why you are on a medication and ask to be taken off them if they are not helping or cause too many side effects.

i concur with @dlydailyhope. get the MRI ASAP. any irreversible damages to the spine makes the rest moot. OK? d
