If the headache is from a chemical exposure that causes an autoimmune immune system ... and that is the cause of the pain, the headaches (whether or not a brain tumor comes along later) ...

then toxicologists will tell you to avoid all chemicals (even meds unless absolutely known to be needed or helpful) or you can add on more harm ... asthma ... things like that

I have never heard doctors say they know what causes an autoimmune immune system or that they know what to do for it.  You hear things like suppressing the immune system and meds for pain, and that's about it

What is the best help I've heard about is glyconutrient food supplements - cell to cell communication help, and the body heals itself

And these are all the kinds of things that this chemical causes

It is the real harm to civilians with CFIDS, the real harm to the Vietnam Vets, the Korean Vets, the WWII vets, the gulf war vets and today's vets.  Not that there are not other things that harmed them, but 2-butoxyethanol is the main chemical of harm in our nation and our world.  THE reason for the epidemica of diabetes (a side effect often) and of NHL ... leukemias and lymphomas and brain tumors and headaches of every type

Note all the syndromes and autoimmune issues today ... and compounding to more and more weird variations.  Many things are autoimmune.
