When I move my head downwards (quickly, chin toward
neck), I feel a choking sensation in the
windpipe area. Sometimes it occurs naturally too, without head movement, but it is intermittent. I do not have a sore throat, or cold, but my doctor gave me a throat spray which is not much use! I can eat without discomfort. Sometimes if I smell something strong, it makes me feel like I want to cough, a strange sensation in the throat and windpipe. What can be causing this?
