Stomach Irritation?

I have a 10cc lap band with only 2cc's in the band. I have these episodes where I think my stomach gets irritated due to heart burn and my band seems to get so tight I can only get fluids down. This happen to me once before when I had 4cc's in the band and had to have 2cc's removed because everything was getting stuck. I have had problems with the band since day one ( I was tight since the very beginning). I am just worried that even if I get the 2cc's I have in the band removed that this will happen again. What will I do if I am too tight and I have no fluid in the band. I just want to say that even before I had the band, I always suffered from stomach irritation from time to time, but now it is horrible because when it happens I can't eat because of the band. I have lost a total of 50lbs. since surgery in Feb. 2010. I was appreciate any input or any stories of any other bandsters that experience this.
