Ok this was so weird. I know it's happened to me before, so it's not just a one-time thing but I just can't figure out why. I was peeling a raw butternut squash with a vegetable peeler and then cut it into chunks to roast. The specific logistics are pertinent here: after peeling, I held the squash in my left hand and cut it into chunks holding the knife in my right hand. After finishing, I noticed that the palm of my left hand was, well, sort of shrivelled and dried up. I washed my hands well thinking that I just had some dried squash juice on it. But no - it just got worse. Eventually, the skin on the palm and fingers of my left hand became so stiff that I could barely open my hand all the way. Then...the skin began to crack and flake off. It was just like a chemical peel! My right hand, which did not contact the squash at all, was perfectly normal. No amount of hand cream helped. This effect lasted about 5 hours. My hand is now fine. Any explanation????
