Re: Difficulty swallowing
Some of your symptoms could be related to blocked Sinuses, Have you had a cold recently.
Pressure in the head and ears and constant blowing of your nose can relate to Allergies.
I have much the same myself at the moment and have a nasty cold,
Smoking will not help your problem.
The feeling of the throat closing or something stuck at the back of the throat along with swallowing difficulty can be caused by PND from your sinuses.
Have you seen your Dr if not then I think you should in case of some other problem.
