Fungal infection spreading

I'd like to start off by saying that I have been suffering with this for a little over 2 years now. I dont have insurance anymore so I cannot afford a dermatologist. I'm also a fulltime student in medical school. I breastfeed my daughter. I have this rash well idk if it is a rash. It is extremely hot and gets really itchy. I apply Quadriderm on it but it seems to not do a thing. I've also tried Klotrimazole and I've used that for a year and still nothing. When I sweat it gets worse but lately it seems really irritated even if i dont sweat. Please help me i am desperate
