I did the same , following low FODMAP diet , when bloating symptoms started . It also came with pain. Thought I was experiencing acid reflux reactions. When it became more frequent, without responding to GasX , etc , unable to lie down to sleep, I started to worry and wonder. So extreme, a to ER was necessary. Though no one else had diagnosed , the ER physician asked me to pony to ares of list discomfort. He immediately said that he thought it was gall bladder related. Brought an ultrasound bedside and it proved his point, stones, signs of inflammation. Result: It was removed. No longer have bloating, but vigilant about watching fats, sugar, carbs until my body adjusts to its absence. Lost 10 lbs . as a result, but that’s ok.
