What Causes Blocked Feeling In Throat Around The Neck?

I'VE FOUND IF I'VE GONE WITHOUT A MEAL AND SOMETIMES SIT DOWN TO EAT I DEVELOP A "BLOCKED" FEELING IN MY THROAT AROUND THE NECK AND SOMETIMES UNCOMFORTABLE THAT I HAVE TO WAIT TILL IT PASSES. I SAID SOMETHING TO THE MED. DR. AND SHE SAYS IT'S SPASMS.
