something in bottom of throat after coughing

[lmoney23]

I get something in the bottom of my throat after coughing and sometimes a sneeze. Not liquid, feels like a piece of food or something strange. When i swallow it goes away. I do have a few other silent reflux symptoms like clearing throat, dry cough and recently light sore or scratchy throat, but from what I've read the "lump" from silent reflux doesn't go away after swallowing.   It does seem to get a little better after taking omeprazole 20, but it is still happening. I read a lot of people with a lump but mine isn't a lump. Any ideas?
