Have you spoken to your Neuro about this?

I sometimes have difficulty swallowing but have never aspirated fluids into my lungs. I believe that can cause pneumonia.

Sometimes my swallowing mechanism seems to freeze. I've learned to just be calm and wait a moment and usually I can swallow. As a result, I've started eating much slower and taking much smaller bites. Also careful with drinking water and coffee. Anything too hot or too cold seems to shock my throat and swallowing is harder.

I hope you'll speak to your doctor about this. He might have a suggestion as to what you can do but at the very least it needs to be documented in your medical records.
