Staples Are Evil

My hand has been bugging me the last few days, but this morning I apparently did it. Opening packages and cutting some things, then a long battle with some very tough staples in old documents. By the end of that, my hand was hurting...and the next thing I know, it's flame red and swollen to twice normal size. I spent that back half of the day only answering the phones. It's killing me. Ice packing it now...
