A milk allergy is an adverse immune reaction to one of the proteins in cows milk. Do you suffer from it?
I'm not really sure.  I never seemed to have a problem with it before, but I cut out dairy a few months ago and now if I drink milk I don't feel so well.  What are the symptoms?
It can vary. Atopic dermatitus, swelling in your throat, and constipation or diarrhea can all be signs
Well I don't get any of those, usually just a bit of nausea.  Maybe I'm not allergic, just intolerant.
Well symptoms can be rapid or gradual so keep and eye peeled for the days after as well.
I will have to do just that.  Can it be fatal?
It can include anaphylaxis which can be potentially life threatening and require epinephrine
Wow, I didn't realize it was that dangerous.  Do a lot of people have it?
