My problem I'd been having for over 20 years turned out to be a nose problem. It got worse over the years. All the time I would have Body Odor s which would get worse when I would eat certain foods. My nose would run too at times when I would eat. I would get treated for constant sinus infections, deal with allergies, and constantly have my nose running when I would eat. But my nose was dry and felt blocked lots of times, with burning pain too. But even when my sinuses were dry the odor was very noticeable.
