Will steroid creams make fungus infections more resistant to antifungal creams? i'm unsure if what i have on my abdomen is eczema or a fungal infection?

The lesions may appear similar. Fungal infection tends to be scaly and itchy. There may be a burning sensation and redness. Eczema may be associated with allergic conditions such as allergic rhinitis. Determine the diagnosis first prior to treatment. A virtual consult with Healthtap.

Won't make it resistant, but could make the fungus infection worse. A dermatologist can tell you whether what you have is fungus or eczema (or something else) and can prescribe the proper treatment for it.
