Our old family remedy for migraines is epsom salt. You take a handful of it (teaspoon or so), toss it back, and wash it down with a big glass of water. I foolishly rejected it for decades it because the doctors hinted that something terrible could happen. (As it turns out, the worst that could possibly happen is a few minutes of diarrea.)
I rediscovered it less than a year ago, and it certainly works.
Folk medicine should not be rejected just because it is not FDA approved. (They're nothing but a cartel with a gun & a badge.) They'll never approve of anything related to epsom salt because you can get a life-time supply for $2. If there's no known harm, and a lot of people believe it helps, it probably does help for some reason.
With the epsom salt bath, it could just be that it's soothing, it could be something about the quality of the interaction when mom gives special attention, or there could actually be some chemical thing happening. No one will ever pay for the research to prove it.
Like the man said,

It can't hurt to try it.
It could be more than a few minutes. Why don't you take a magnesium supplement instead? It is BETTER!
