Smells come out of our pores all the time. Consider some of the foods you eat. If you have been to the doctor and they find nothing wrong with you, monitor your diet and experiment taking different things out of your diet. My step daughter used to smell like urine all the time. She was clean and never wet the bed or her pants, we did just this and found several things that made her smell like urine. Sometimes you just have to experiment. It is certainly nothing so serious as to take your life.
Everybody tells me is all in my diet, I think i'm going to look into that, Thanks!!
