I have recently developed these same symptoms. I am at a loss. Did you ever get a diagnosis regarding these symptoms? I am desperate for an answer.
I know its been 4 years since your post about the same smell coming from your feces and sweat.I was wondering if you ever found out the cause? I am suffereing from the same problem right now.It started in my feces and is now in my urine,sweat and I can occasionally "taste" the smell in my mouth.Doctors don't seem to think its a big deal.Thank you for any response you might have
