Windfire

I have been having some troubles this past week with my band. I might be paranoid because I am the 1% that had to have a second surgery because my band slipped. I have been having spells at night where I wake up choking. It burns my throat really bad and I usually cough to the point of vomiting. I have made a few changes like changing last time I eat and what I'm eating in the evening verses the day. Now I'm having this feeling where sometimes It REALLY hurts where the band is. It will last a couple of seconds and then seem ok but will come back maybe 10 minutes later. I'm getting fluid down but only little. I have already put a call into my doctor but what I would like to know is if any of you have experienced the same thing. Sometimes when I'm swollowing fluid it REALLY hurts too. I don't know what to do
