I have a hiatal hernia, at times it will cause acid reflux, but, I am able to eat dairy products and drink
milk. You could very well have an intolerance to
milk products, thus causing the uncomfortable feelings.
I would see a gastroenterologist and have gall bladder ruled out and also an upper GI to make sure there is nothing else going on. Also, a food allergy panel for dairy products would be good to have as well to see if you are indeed allergic to those types of foods.
