I'm okay with having milk in tea or coffee or cereal, but if I drink milk or milkshake alone I get a huge painful bubble in my stomach and chest, that I call a 'milk bubble', and it's really hard to pass (burp out), but feels too big to go anywhere except sit in my stomach and it feels like I have an inflated balloon inside my stomach and just want to burp.
I manage to burp after a while, which often tastes and smells foul, but it relieves that bubble pain.
Does this sound like lactose intolerance or is it just me?
