[/INST] Hello, Yeast infection can occur between skin folds, such as in your groin area and under your arms. Yeast can also take up residence in your belly button, especially if you don't keep it clean and Chat Doctor.  Candidiasis in your belly button causes a red, itchy rash on your navel and may also cause a thick, white discharge. Therefore, I suggest consulting a skin specialist for physical examination, diagnosis and treatment. Hope I have answered your query. Let me know if I can assist you further. Take care  </s>
