Severe skin issues. Persistent issues with your skin or issues that keep coming back might well be signs of a Candida infection. Persistent rashes or dry or itching skin may all be signs that you have a serious Candida infection. Sometimes you may develop eczema, and your doctor may prescribe steroids that seem to cure it. If it comes back again and again, it could be a sign that you have a serious Candida problem. There are tests for Candida available that you can do in the comfort of your home, or you can consult your doctor.
