Lately I’ve noticed each time I have a dairy product

Patient: Lately I’ve noticed each time I have a dairy product I get a little bump on my skin that is barely noticeable but itches and when you itching it it turns slightly pink then goes away back to skin tone color I recently cut out dairy completely but now I found there’s even more on my stomach what do I do I also am already gluten free.
