I don't know what is going on but it's very annoying. I don't have any rash but if I even rub where I itch then it becomes welts. It didn't happen for about 3 days so I thought it was gone. I really wonder if it's the minerals that my husband works around. He comes home and crashes so all the minerals get on the bed. I read somewhere that sulfate allergy are like that when you sweat it out of your system. And he works around a sulfate poatate or something like that. Who knows I would just like it to stop. Why I think it might be that is because I didn't itch the following days he didn't work.
