Food keeps getting stuck in my chest area

I had my lap band surgery almost a year ago. I had my last fill in June and was fine for 1 month. Then I started having trouble getting things down, it's like things are getting stuck in my chest. It's very painful. It even happens with just taking some sips of a drink. I've only thrown it up a few times. I thought it maybe my band was too tight, but why was I fine for a month. Does anybody know what could be causing this?

No I do not know what is causing it. I would call the doctor. Please find out. Trouble means you need to be check out. imaluckydog
