It is neither lactose intolerance nor true allergy. It seems to be a sensitivity to casein and whey. The very mild reaction I seem to get after just a trace amount is only a stuffy nose. I did consume dairy for about 40 years before going off of it, so I know it wouldn't ever cause a life-threatening reaction for me. I think the only symptoms dairy generally gives me are sinus problems and gut issues. I had thought that I'd be able to tolerate at least trace amounts without a problem because of the fact that it isn't a true allergy. I guess I'm just confused about whether more is automatically going to be worse or if it could end up just being the same reaction as a trace (which isn't that big of a deal if it's just a stuffy nose). I'm also a little confused about why I'd react to a trace even though I've had dairy all my life up until 3 months ago. I don't know whether to interpret it as needing to stay away from all dairy forever, or whether I should experiment with adding some dairy back in to see how much is really too much.
A trace amount gives me such a mild reaction that I just don't know what it means.
