What Are The Side Effects Of Creams Containing ETDA?

I recently started taking a rub-on cream that supposedly helped my swollen ankles and my arteries. It had EDTA in it, and evidently I am sensitive to it as after a couple of days, my walking was really unsteady; it is not too good after two bad hand-held falls, causing injuries, but I really had to be extremely careful in my apartment so that I did not fall. Outside in the halls, I use a walking pole. I searched for some information re. EDTA but I think that I didn t find anything bad about it. But it does not check out for me. Vivian Walz
