Allergy to cow's milk is a common food allergy that can cause a range of different symptoms. Common symptoms include skin reactions such as rash or itching, stomach problems such as abdominal pain, vomiting and diarrhea.
If you suspect that you are allergic to cow's milk, you can test yourself with a blood test that measures your levels of IgE antibodies in the blood. If the levels of these antibodies are high, this may indicate an allergic reaction to cow's milk. This is an indication of allergy. It is important to seek medical attention and get a correct diagnosis and treatment in case of suspected allergy to cow's milk.
