Think I got the same, but not through shakes.

I think mine is down to the attmosphere and moisture. I'm pretty sure it was worse over christmas when working out in a gym with a comfortable temperature and getting warmed up during the workout ... then going out to the freezing cold straight after.

The same happened in the shower. If I got out the shower and went straight out of the room, my skin would dry up a tad and red patches would appear ... if I stay in the bathroom where its still warm and steamed up, my skin is fine.
....oh, and it happens on my back and shoulders aswell.

In the summer time, it might not happen as the ambient temperature outside is slightly warmer, so its not a big hit from going from a warm building to a freezing cold outside.



.... all my thoughts of course
