I've never had this problem until now...here's the story. Well, I was outside the other day, and it was freaking cold out. Probably about 9 degree's F. I was wringing cold water out of a towel (long story) and the cold really hurt my fingers. First my fingers felt cold, then nothing...just this buzzing sensation. Realizing that wringing water out of a towel with bare hands at 9F is probably a stupid idea, I rushed indoors and defrosted my hands with warm water. But all I felt was buzzing, not warm water. Hmm. So today I was melting wax in a soup can in boiling water, and I touched the tin to see how hot it was. It didn't feel hot, so I just grabbed the boiling hot tin of wax and poured it into my mold. The wax dribbled onto my fingers. I didn't even notice it! Later that day it occurred to me that maybe i was having trouble feeling how hot things are, so I experimented. I ran hot water over my fingers, but it didn't feel hot at all. It just feels like my fingers are buzzing or something. Stranger still, if I IMAGINED that the hot water is cold, it suddenly feels cold! If I imagine it's hot, I get that buzzing sensation. It's probably just a temporary condition, so I was wondering if it's ever happened to any of you folks?
