To follow up, no soap seems to help (in fact, that makes it worse). And no witch hazel, aloe vera gel, AVC, betonite clay etc. can help so if you have this problem as well, please do not waste your money. I have also tried to sweat out the toxins through regular saunas (every day. yes. every day.) for about three months, but this seemed to only aggravate it, confirming my theory of an infection. I also sweat more than the average person (but not hyperhydrosis because it is only from my armpits) which makes me think I am correct that it truly is an infection. I think I shall get a bacteria culture done. I will keep you guys updated.
