I have this red rash (maybe fungus) on my inner thighs. I’ve had it for a couple of years but never done anything about it. It has now spread to my lower back. It doesn’t itch at all or cause any problems it’s just weird to look at. If this helps, a doctor noticed it during a physical and told me to get this type of shampoo but apply it to my body. If you know what kind of a shampoo he was referring to there then that would help. Thanks.
