I have had this body odor for ten years now, since high school. I used to be obsessed with hygiene, showering, scrubbing my underarms and applying deodorant up to 3 times daily. Since about a month of that continuous regimen, I developed a rancid like smell. The smell would permeate an entire room. My odor started to smell like burnt butter, rotten cheese, garbage, etc. I dont know if it was an over irritation of my armpits/ apocrine glands, but nonetheless, I have not been able to lead a normal life since and have had the same issue. Except I think its gotten worse, even though I dont shower 3 times daily anymore. Only once a day and I cant use regular deodorant anymore bc the smell becomes unbearable. Strange thing is that my friends, family and colleagues have never said anything to me. They can smell the odor at times when its bad, but thats because it permeates the room and cant believe its comes from someone. Bc it does not smell like normal body odor. I know its me bc wherever I've gone different people say, "whats that smell". My life has been miserable bc I'm so self conscious about it. If anyone knows of a cure for this, you will be my savior. Any sort of help is appreciated. As everyone knows, this is a terrible thing to deal with and I sympathize with anyone who deals with this each day.
