Bad Odor When Drinking Anything?!

Hello everyone. I wanted to see if anyone else had this odd symptom. Whenever I am drinking (and it can be anything; water, whatever) I am able to smell a bad odor (possibly fecal-smelling). I smell it when I am inhaling through my nose while drinking, to be more specific. Does anyone else experience this or know why it happens? I wonder if it could be breath or sinus - related (perhaps the action of drinking allows me to smell my breath or something in my sinuses, such as an infection - I'd rather one of these be the case as opposed to the smell coming from my body!). Any and all comments appreciated. I'm just trying to figure out if this is a breath/sinus odor or Body Odor .
