Recently, I can't keep warm and get chills, even with blankets and layers of clothes. Ear temp when I get like that is 96.1-96.6. Is that normal?

Cold intolerance. Cold intolerance can be caused by an underactive thyroid gland or anemia as well as being very underweight (ex:anorexia). Certain medications such as beta blockers or anticoagulants can also cause intolerance to cold in some patients.
