Do you know what a Material Safety Data sheet is? also called MSDS, or SDS?  It has toxicology information on it.  It might be helpful for your doctor - maybe.  If you know how to read it, it might be helpful for your doctor.

Here is a link to Roundup Powermax on the CDMS website.  scroll down to the bottom of the list, and you will see: "SDS 5/29/2015".  That is what I am talking about. Open that document, print off a copy and take it to your doctor. 

IF you have been using a different brand of glyphosate, you can do a search for it - click on product search, type in the product name, and then go down the list until you can find "MSDS" or "SDS".

I would think that the information in the SDS would be essentially the same for all glyphosate products, but I could be wrong on that.
