Can dairy allergy cause fluid to build up in your ear?. would dairy allergy show up on a food allergy test? i noticed fluid build up when i eat dairy

Milk allergy: can show up on food allergy testing either skin or blood test. Whether milk allergy can directly cause fluid build-up in your middle ears (not the external or inner ears) is unlikely; indirectly though, through inflammation of the upper airways that can happen in some people with milk protein allergy, that leads to blockage of the Eustachian tubes hence fluid build-up in the middle ears,
