Which of the following is true, according to the conversation?

M: My toes feel very itchy, Jenny. It’s really irritating. I don’t know what’s happening.
W: Let me take a look. Ah-huh, I think you have athlete’s foot.
M: What are you talking about? I’m not an athlete!
W: Come on, John, stop joking. You’d better take care of it before it gets worse. Imagine you have pus gushing out and rashes all over your legs....
M: Stop it, "Dr." Jenny.
W: OK, OK. I guess I’ve got some cream for it. It really fixes skin in trouble. It’s really a help for irritations and blemishes.
M: Is it this one?
W: Not really. That one is for heat bums.
M: Have you had athlete’s foot before?
W: Yeah. It was a very bad experience. You know, if you don’t keep your feet dry and clean, the fungus will grow and spread out quickly.
M: So my case isn’t that bad, huh?
W: You’re lucky. Yeah, here it is. Now apply it to the affected areas. This cream is very effective in clearing out bacteria and stopping inflammation from developing.
M: I hope so.
