Lots and lots of people have mild food allergies and don't know it, because the symptoms are subtle, often delayed and last up to four days after you ingest the food.
Milk allergy is different from lactose intolerance. Most people of northern European heritage are not lactose intolerant. Most people with other genetic backgrounds are. But it's definitely possible to be allergic to milk but not have the digestive issues of lactose intolerance (I am).
Most allergies develop via repeated exposure to the allergen, so you're most likely to be allergic to foods that you eat most days, or grew up eating. It can be really hard to break the habit. Your body will also have physical cravings for the allergenic substance, besides the psychological hurdle of eliminating a staple from your diet.
What I tell everyone is, just try it.
The best way to do it is with a challenge diet where you eliminate all common food allergens for four days, then re-introduce them one by one. But there are a lot of them (dairy; eggs; all grains except rice, including ANYTHING made from corn which is just about every processed food on the market [and noting that buckwheat, quinoa and amaranth are broadleaf plant seeds and not grains, so they are okay]; yeast including ALL mold products, vinegars, alcoholic beverages, mushrooms, miso, tempeh, soy sauce and processed fruits; soy; chocolate; shellfish; peanuts; tree nuts - and that's just what I can think of off the top of my head) so doing it the right way takes a lot of commitment and a hypoallergenic cookbook.
Less accurate but much less hassle is to just eliminate the one substance you most suspect, like dairy in your case. Four days without it, check how you feel, then reintroduce it and note any symptoms. Repeat the challenge if you're not sure. Of course if you're allergic to other things too, the results will be cloudy, but you can usually tell when the allergic load on your body is reduced.
Just FYI, this is all information from my MD allergist. I know there are people whose heads explode if something seems "new age-y" to them. But this is sanitized, dualistic, symptom/body system-limited American medicine all the way
