question: My wife has been getting a rash on different areas of her body when she scratches it.  If she stops scratching it, it goes away but feels itchy and then scratches it and a rash appears again.  Been getting it for a few weeks now.  I have been putting Lanecane on it to help take itching away for a bit.  Just wondering what she can use to help with the rash. She's never gotten it before but wondering it might have been caused by recent floods in the Calgary area and something being released in the air.  She has never had this before.  Thanks
