I Have Full-like Feeling At The Base Of My Neck

I have full-like feeling at the base of my neck - meaning it feels like something is stuck there. I thought it might be indigestion, which I have only had while pregnant. I tried taking antacids, but they have offered no relief. I don't have any burning sensation behind my heart (like heartburn). I did have a mild sore throat with some difficulty swallowing a day or two before this happened. I no longer have a sore throat. It is annoying, and I was just looking to see if it was food related (as in indigestion) or something else.
