I get this off and on. It's most noticeable when I don't get enough sleep. I recently spent two months on the graveyard shift and the miserable-freezing was daily for me. For two weeks, I've been back to the shift where I get as much sleep as I need, and it hasn't happened since.

The warm-me-up aerobics work, but not for long - maybe 15 minutes. Something else that works for me (temporarily) is coconut oil. That'll have me tearing my clothes off and sweating.
