I've recently been diagnosed with early stages of argyria as a result of taking Colloidal Silver for too long. - over 5 years
long story short, I took too much for too long and its beginning to show on the tops of my hands and finger nails. Went to the hospital to rule other issues and biopsy returned silver accumulation.
will go see dermatologist in two weeks to discuss possible treatment.
figured it was worth sharing and documenting a genuine case of argyria for once for the sake of information sharing.
