Please do not wait, this happened to me a month ago, I called my Dr. and I had to go to the emergency room in rochester where I had my surgery. They had to take out the fluid in my band I was hurting so bad in my chest and vomiting couldn't even keep my saliva down. Call the hospital and have your Dr. paged. I went back after 2 weeks and he put the fluid back in. There was some food stuck and blocking everything going down. Good Luck!
