I actually seem to run hot when my empathy is going strong. And I have heard that same running hot comment from others on this site. But often I will feel a cold breeze from the knees down when there is no source of air at my house. And quite often at home I walk into a room and it is way colder than it should be. As an empath I know I attract spirits and assumed that was the source of the cold.
Since you get cold to the point of being numb I wonder if a medical check up would be a good idea to rule out low blood pressure or anything else?
