Your gut health has a direct impact on your lower back. If you are intolerant of some foods, when you inflame your gut, your lower back can end up in pain as well.

I'm intolerant of a milk protein. I can handle the bathroom consequences, I can't handle the lower back consequences.

Interesting. I’m starting to suspect dairy. I just tried switching to a2 milk but didn’t notice a difference. Have you tried a2 milk with the a2 casein protein?

I have not. I'm rarely in a country where that is available. Usually when I'm in the states, I'm not willing to experiment with it on my one week visit.
