What is the difference in symptoms of dairy allergy vs. Dairy intolerance?

Allergy not just GI. Dairy intolerance is caused by an inability to digest milk sugar lactose into two simpler sugars. This results in gas, cramps, bloating, flatulence & diarrhea. Dairy allergy may cause these same symptoms but typically also causes vomiting, skin rashes like hives or eczema & even triggers allergic rhinitis & asthma. If symptoms all GI try lactose-free milk. You'll have no symptoms if intolerant.
