I did the Whole30 in September 2016. Shortly after I completed the Whole30, I started getting hives every time I would work out. I started at a new gym at the same time so I thought for a long time that I was allergic to something they were cleaning the gym with. It has taken me until now to realize that the Whole30 could have uncovered something I am intolerant to and I still get hives every single time I work out. It takes somewhere between 1-2 hours for the hives to go away.
Has anyone had a similar problem? I'm sure it's a food allergy, but the fact that it's only triggered when I work out is what is stumping me.
Any advice is welcome. Thank you!
