PEA / Palmitoylethanolamide experiences

Anyone experiences with Palmitoylethanolamide / PEA?

I bought it in powder form, to my knowledge a very pure product.
Started with it, and within a few days experienced hives flaring up. I have no history with hives, at first I couldn’t believe it was due to the PEA supplement so I stopped all supplements, it took many weeks to settle down.

When everything was back to normal, I tried PEA again and after just two days another instances of hives flaring up…

I would love to hear experiences regarding PEA in general and of course if someone had a similair experience or explanation what I had that would be very welcome.
