Your possible problem

This has just occurred to me,but have you considered that you may have a sinus infection? I remember reading a case online about somebody who thought he smelled horrible,and he could smell it everywhere he went. He also said that he smelled of feces! But it turned out that he had a sinus infection and got rid of it by taking Antibiotics .

Here is the post:
Here was my experience. Historically, i had cronic inflammation in my sinuses caused by allergens. Caused headaches, sinus pain and frequent sinus infections. Most recent infection took a nasty turn. I began smelling and tasting feces everywhere I went. If I sniffed hard, the odor moved to the back of my throat. My wife commented on noticing the odor as well. I went to see the doctor who diagnosed the chronic inflammation and said there was no doubt that the feces smell was a sinus infection. He hit me with three things at once. Nasocort for the inflammation, a dual Antibiotic for the infection and an over the counter sinus rinse to flush out bacteria and dust. It took about two weeks but the fecal smell went away. Now I take a 24 hour antihistamine for the allergies and I use the nasal flush daily. Obviously there could be many different causes of a fecal smell and my experience only covers one cause but I hope it helps. God Bless Tweet
