|Do you have other health ailments? If so, do you remember a time when your eyes burned & hurt and your urine turned dark and a FATIGUE hit ... after 'flu-like' symptoms?
2-butoxyethanol affects so many parts of the body: joints, cartilage, blood, immune system, nervous system, could be any of the*glands/organs, kidneys, liver ... a lot of things. However, if you don't have more than one thing wrong, don't suspect this chemical.
Other things that would most likely show up with it, would be this for fatigue:
Shortness of breath
Rapid heart rate
Yellow skin color (jaundice)
Eyes burning & hurting (with initial exposure - flu symptoms, too)
Red blood cells immature
Blood in Urine (part of autoimmune hemolytic anemia)
In addition there are many times, off and on, Horrible Headaches!
The Central Nervous System damage gets the most attention, things like:
Short Term Memory Loss
Look at this list, and tell me if you (or one of your parents) had these symptoms. (It is a teratogen that has been out there since 1930's so singular items can show up as birth defects)
I strongly suspect it for causing most of the autoimmune health ailments of which joints can be one. BUT the USA doesn't realize this. http://home.gci.net/~blessing/pages/drUssery.htm
Yes, these may all be from an autoimmune immune system, but the USA doesn't realize that.
Why doesn't the USA know that this chemical causes an autoimmune immune system?
