I am not sure if this is a cause for concern, but I received the following rash/discoloration on my armpit. It's bilateral, I have no other symptoms, it's not itchy and does not have a particular odor. I think it could be a fungus infection but I am not sure what the underlying causes would be. Any help is appreciated,
It does not look like a fungus or a rash. From the photo it just looks like a stain.
You do not have any underarm hair. Have you recently shaved the underarms or used any hair remover that could have done this?
If your underarms start to get itchy, sore and shiny then get it treated with an antifungal cream.
