Could I be allergic to milk?

I have a milk allergy, can I be allergic to soy as well?

• I am a 15 year old. I've been diagnosed with a milk allergy. When I consume milk, or any kind of milk protein or whatever, I have an allergic reaction. My throat burns like acid in this one particular spot. It's in the back of my mouth... Like, you know if you suck snot from your nose into your throat, the hole it comes through? That's where it hurts. I also have had recurrent sinus infection for 9 years now. I'd get them non stop. I figured out that the milk causes it. I have milk, my throat burns instantly, and within days I'm stuffed up, have headaches, TONS, I mean TONNNNSSS on mucus. The whole deal. I've noticed that I get the sore spot in my throat at random times too... I'll check my labels and I don't see any milk or milk ingredients either. I'm vegan, so I'd know. I have a lot of soy products, tofu, soy milk, soy cheese. Could I be allergic to soy as well? I think I'm going to cut out the soy and have almond milk instead just to see.

• Answer:

  People allergic to one thing may also be allergic to others as well. You should have your allergist test you for the commonest food allergies so that you'll know. Soy is a common allergen, as is cow's milk. There may be other foods that you're sensitive to as well.
