Hi Jany. I know someone who has been dealing with this for years, and has seen every expert imaginable. It turns out it does have something to do with 'leaky gut syndrome" and copper levels. And something to do with calcium. Thats all I know right know, but she does use high grade fish oil to deal with associated joint pain. She also has hair loss problems. Shroom

hives are usually from allergies.

common allergy things: milk, nuts,wheat

some detergents used to give me massive hives when i was a little kid.
Tide put me in the ER at one point. i was VERY allergic to stuff like that.
