Are you being exposed to mold? Do you feel better away from your home or work?
Please don't dismiss this possibility if your house is modern, and doesn't have that nasty musty smell. Only a tiny amount of mold can hurt you if you are sensitive. Houses in Northern America are built in a way that there is a possibility of mold forming inside the walls etc.
Where I used to live, we had a problem in our bathroom ventilation system, after two years of living there a plumber came and said that instead of sucking the air in, the fan actually did the opposite... We've been breathing the air from the vent piping. There was also a completely dry mould stain on the wall from a leak that happened and was fixed long before we even moved in, but dead mold is also dangerous. In that place I had symptoms of sneezing, dry eyes, terrible headaches, but I was functional, my symptoms were pretty "flat" and consistent. After we moved in a different place is when i became severly ill. The symptoms you experience depend on the type of mold you're being poisoned by. I still don't know where the mold is hiding in the house we're currently living in, however, the house is old and has wooden floors, the climate is damp, and now that I am away from the house I feel better. Please consider this as a possibility and think about
it. I was sick for a year (seeing llnd) when I suddenly realised that my problem is mold, I just thought until then no, no musty smell and I can't see any, so we don't have mold in our house.
My borrelia test result is also weak positive, I probably have it, and it is maybe the culprit that turned on some epigenetic switches for me to become sensitive to mold, but my acute problem that I could have died from is mold. Yet we only treated lyme for so long..
As famouls LLMD M.R. says, before treating lyme, make sure it's not mold illness. I wish everyone treating lyme did this.
