Food Allergies Treatment

When I was a baby I had an allergy to milk. It caused me to have eczema as well as other symptoms. Supposedly I “got over it” but I’m thinking I’m still reacting just in a non violent way. I am overweight and I have skin redness which seems to be rosacea, oily/dry skin, and a tendency to have many blackheads on my face not so much pimples. Basically horrid skin in my opinion. Could this be what my body does from drinking milk or eating it’s products? Am I still reacting allergically just not the severe way? I’m really looking to see answers from people who have had these problems and cut down on milk and saw a change. Thanks.
