I had a (major) headache everyday for about a month and a half and could not figure out the source. I went to the doctor's office and got medication which had very little effect. I then had to leave town for a few days and suddenly they went away. Upon return they came right back. I had an "Ah HA!" moment and figured we should test the corn stove. Whenever it was started I would get a headache within a couple of hours. After turning it off it would take about a day for the headache to clear. We would leave it off for a week and I would have no symptoms but as soon as it was turned back on again they came. We enjoy our corn stove but there is no way that I can deal with this kind of pain every day. Does anyone have any ideas as to what the problem could be? We have carbon monoxide detectors in our house and they have never gone off. Also, neither my husband nor my two children have had symptoms. Our house is very tightly sealed as it had been completely renovated inside and out within the last year. Could it be the stove or the corn?
