I was talking about hygiene with my partner who is a nurse and they were telling me that a lot of people remark that their armpits are smelling worse than normal and they are using more and more deodorant and people just think it is normal.
Trichobacteriosis looks like a yellowish coating on some of your armpit or groin hair and you need to shave and wash the area every day for 2 weeks. It is more common in men than women in the US only because it is more common for women to keep their armpits shaved. Most of the patients who are affected by it think that its actually residue from the increasing amounts of deodorant they end up using.
Hm. I don’t have any yellowish coating that I can recognize, but my stank smells different than it used to; it’s a bread-like smell. Could this still be what you’re describing or something different?
You should look at yeast infections of skin.
Bready smells are typical of yeast, this post is talking about bacteria.
