Coco2009

Hi - I had lapband surgery in Sept 2009. Last night I ate chicken which sometimes gets stuck. I tried to eat it slowly but probably ate too much. I had the familar feeling of food being stuck. An hour or so later, it still hadn't gone down so I tried throwing it up. Some food came up, but in the process, I started to get lots of pain/tightening in the center of my chest. During the next 4-5 hours, I got up and would throw and the pain remained. I didn't throw particularly violently - it was normal "lapband" type of throwing. The pain is milder now but still there. It hurts more when I twist my shoulders. Does this sound muscular? or could the band have slipped? I'm not having pain down my arm or in back so I don't think it's my heart. Thanks in advance for your response!
