I have same problem as well but for me it got even worse. It all started three years ago at high School when I've smelled something odd about myself. That I've could smell manure or faeces coming out of me I thought first it was coming from the bottom of my shoes but there wasn't anything their. Sometimes the smell would go away come back again. I try to annoy the people who were talking about me that I smell but it left me embarrassed. I still went to school and work with this embarrassing condition. The oddest thing that my family couldn’t smell me I ask my friends if they could smell it but they’ve said no. But sometimes they either ask me if I’ve stepped on something or that if I farted but I couldn’t feel anything moving out of me and checked my shoes. I have shower everyday and I wear clean clothes. I went to three doctors and they’ve said they couldn’t smell anything. So they thought I had paranoid illusion – thinking that I smell. I visited more then five doctors eg. Gastroenterologist, Phycologist, Neurologist, etc but they couldn’t find anything what was causing it. So when I went and researched about I found that there were seven causes of body faeces odour.
Now I’m ordering to get vitamin K. I’m still waiting for its arrival. Some studies have shown that intake of vitamin K can control faecal body odour."
