I have been having issue with heat in close proximity to me and horrible headaches. What I mean by this is when I am in a room or space with heat coming directly near me I get a horrible headache. For example, I work from home and where I live it is currently 45 degrees outside so I use a space heater in my home office to stay warm without turning up the furnace. I noticed this has been giving me bad headaches and they go away once I am out of the room with the heater for 20 minutes or so. I have also noticed I get headaches when the heat is on in the car, again a closed space with heat blowing right near me. It has even occurred when I am sitting too close to a heat vent in a room. I do not have my space heater running today and I am FREEZING but no headache. I am drinking enough water so that is not the issue. Has anyone experienced something similar? How did you deal with it? We are coming up on winter and I cannot go without heat in my home and car.
