Yes, I have had both of these happen. One, if you don't chew your food enough, it hurts going down and I too get the back pain. And if it goes down wrong I get the froffy stuff you are talking about, it is discusting. If you just got filled, you should be on liquids for a few days, for your system to get used to the band being bigger. I would stick to liquids, soft foods and work your way back up. Then hopefully you can avoid the back pain and the gross slavia. Take your time eating and don't eat too much!
