Hi! I have had the bad fecal and bleachy odor when I sweat and it's horrible! I went to the doctor and was told that my magnesium levels were sooo low. I began taking 400mg of Magnesium Oxide that the Dr. prescribed. That was a couple of weeks ago. The odor is gradually going away!! I can completely understand what some of you are going through. I was depressed and didn't want to go anywhere that there would be a crowd. Hopefully this helps someone to get checked with the same problem. Low Magnesium levels can cause sooo many issues. Good luck!
