I do not get a closing sensation but I have an issue with anything being around the front of my neck. The last hair cut I had the guy wraps the apron around my neck with tissue paper. I asked him not to do it so tight and put my finger in between to loosen it up. He got offended and said "It's just tissue paper". The smallest pressure on my throat makes it seam like I am being smothered. My Brother wanted me to carry his hat around my neck by the string. I told him I couldn't after trying. He said "Wow your being overly sensitive."
I do choke quite often and some times just aspirate on my own saliva.
Sometimes when I take my meds I notice that I haven't swallowed. I don't know why I delay but I don't hesitate on purpose. I do it with water and coffee too. a minute or to later I realize I still have a mouthful of water.

My pulse ox during the day 92-96. I use a cpap at night for sleep apnea.
