Hello, I have a rash around my underarm area on the upper area and around my armpit. I currently believe its due to a reaction to an antiperspirant/deodorant. Is this correct, or does it look more like psoriasis, a bacterial infection, or fungal infection? After stopping the suspected deodorant, the itch is mostly gone, bur unsure if it's because I haven't been sweating as nuch. https://imgur.com/a/xwq6vvG
