Reply #7: It's called contact dermatitis

If it had been a true chemical burn, there would be tens of thousands of people with the same reaction. There has been only one other.

This is very typical for contact dermatitis when the offending substance is kept against the skin over a long period of time.

As much as we'd all like to blame Wally's and their Chinese vendor, it's simply not the case this time. It's an allergy.
