@houseman36 Has anyone considered allergies as a possible cause of your headaches... maybe something inside your house? Some possible causes of this could be something like mold growing somewhere, in the sink drain pipes, from condensation around showers, and anywhere if there has been water leakage. Do you have pets that produce dander like dogs or cats? Have the air ducts been cleaned in your home? I know all of that affects my allergies. I do allergy shots, and use HEPA filters in my home. Dust triggers my allergies a lot and it is a collection of anything that floats in the air, dander, mold spores, dust mite feces, dirt from air pollution and combustion. I do have cats and didn't realize that they were a cause of my breathing problems, but with some changes at home on how I use the air filters, and covering my bed with sheets that I wash often (where they hang out), it made a big difference. Keep looking for a cause. If your symptoms get better away from home, it might be worth looking at your living environment or even outdoor allergens in the area where you live.
