Probably not the answer to your situation, but there are 2 kinds of cow milk: A1 and A2. It’s a different protein, and it turns out many people are allergic to the A1 type, but not A2. Commercially, “milk” is usually the A1 type. I’m not sure if the milk you drink just happens to be from an A2-source? It’s not labeled, so there’s no easy way to tell.
