I m a 58 WM, I seem to have a very bad odor from my passing gas, not trying to be funny. Much worse than I ve ever had, and more frequent. When I take my pants off the smell in the evening or to use the restroom, it is still on me even though I haven t passed gas for hours. I shower every morning. I m worried something maybe wrong even though I ve recently had a good checkup, labs and all. Please advise your opinion.
