Food stuck

I've had. "Stuck" feeling after I eat for a week. Have dr appt tomorrow. It went away for a day or so now it's back. I can eat, drink, breath fine but feels terrible and keep trying to belch it out too. For last few months I've been getting gas bubbles in my chest as well, about once a month. Hirt like hell! But maylox gets rid of it. Since the stuck feeling started last week I'm also getting pressure in m face kinda like if I were holding my breath... It's all very strange. Any clues as to WHAT the devil is going on with me?

I had it after swallowing two big pills. Took days to go away!
