I use to get real red on my neck and chest, and had these ferocious looking patchy red/brown areas on the sides of my neck (sun damage I assumed).

It all went away after a couple months of EDTA and DMPS IV's. I was really amazed at that, especially that the patches (about 2" by 2" square) on the sides on my neck cleared. I never made a connection to heavy metals for that till they faded with the chelation.
