About a year ago, I noticed that while doing anything physical, I start to sweat on my head and face. The sweat literally runs down my face and drips off and my hair gets soaking wet.

When I go to bed, I put on my celing fan to medium high, open my window, sleep naked and use only a sheet with a very thin blanket over me and DO NOT get cold. The outside temperature is 10 degrees.

I have a fan consistently blowing below my desk at work. Without it, I get to hot.

This is not hot flashes, bed sweats, or the likes. I've passed that stage five to six years ago. These conditions, as mentioned above, started about a year go. There have been no major changes in my life. It's been pretty steady!

What can this be?
