My tingling was concentrated in my feet and lower legs to begin with; lately I have noticed it in my arms at times as well.
My basal body temperature (FIRST thing in the morning) is always about 1° lower than it should be. Through the day my hands are ALWAYS cold. In the evening I watch TV with a coverlet over me because I get cold easily. Through the night I go through "hot, cold, hot, cold,..." and adjust with "sheet off, sheet on, sheet off, sheet on...." Less than restful!
