Have seen black specks in pee off and on for a month. I only see on or two pepper size specks when this happens. It does not occur often, like once every week and a half to every other week. I have no pain, and drink a lot of tea and recently started drinking more water so pee color is normally light light yellow. I have tons of energy as well. I noticed the specks upon adding apple cider vinegar to my daily regimen a month back. Today I noticed one and got it out of the water and it was not hard but soft and broke down into powder. I am really concerned and nervous. I just realized I gave the incorrect email. You can reply to me at careny.gra YYYY@YYYY
