Being allergic to dairy is "not" the same thing as being lactose intolerant.
A dairy allergy involves the immune system, whereas lactose intolerance is a
digestive system issue.
Many of us might think that "oh, they are close enough" for signing -- but:
one can kill you,
the other tends to just make you "feel" like dying.
Huge difference.
Of course there is a range or spectrum of reactions in both conditions.
This is not medical advice but rather intended to get you thinking that "gee"
maybe we should not be signing MILK ALLERGY to mean lactose intolerance and
maybe we should just do the work of learning how to spell lactose quickly.
A better approach seems to be:
"CAN'T TOLERATE fs-LACTOSE."

I've seen MILK ALLERGY used by some skilled signers to mean lactose intolerant.
I am not satisfied with that approach.
Those of you into deep dives, ask AI: "What is the difference between being allergic to dairy and being lactose intolerant?" -- and then click on some of the reference links to make sure it isn't hallucinating its answers.
