I'm going through the same exact problem. My hernia was caused by the band being over filled, and constant vomiting. I too can't eat much and am physically miserable. The DR. office said the next step would be to go look at the band under fluoroscopy to see if the port has flipped over and that's the reason why the dr. couldn't enter the port. Keep me informed on what happens to you and we can compare. You're not alone on this one. It suck to feel like crap when all you want to do is get healthy!
