Gee, Linda...that sounds scary! Did you have to take something for it? Was it something in your yard? Have you ever reacted to anything like that before?
This morning DH asked me if I had cleaned my Felcos after the "PI mess." No, I hadn't,.... nor the shovels, or worse...the leather case for the clippers. And I've used all those since..... I wiped 'em down with Mineral Spirits, figuring it was the first ingredient in the Tecnu. 'Going to clean them one more time....can't just toss them!
