Why do I periodically have a problem with food blockage in my throat. I can go for weeks with no problem, then suddenly take a bite of food and it sticks part way down my throat Sometimes, if I can relax enough, it passes. Other times I usually go into the bathroom and try to force regurgitation. I do nnot have a problem breathing, but do produce copious amount of saliva and my eyes tear up and often my nose also runs.
