Need to get proper antifungal regimen, as this looks like tinea incognito ( fungal infection worsening​ after steroid cream usage). It can be cured, get your random blood glucose test done. And visit a doctor

Fungal infection tends to affect folds of the skin, moist areas like groins, armpits, mouth, genitals, under the breasts, webs between fingers and toes, etc. Our skin protects us from fungal/yeast attack, but any cut or break in the continuity of the skin can allow penetration of fungus. It gives rise to rash, eruptions, redness, burning, intolerable itching and abnormal discharges at times. Fungal infection tends to last for many years if not treated well. It is also contagious. 1. Make sure no one around you has it 2. Take a proper course of medicines 3. Absolutely Avoid using preparations like Quadriderm Four derm Betnovate c etc which contain steroids. 4. Wear loose fitting cotton clothes 5. Don't share towels etc 6. Of late lot of resistance to medicines is seen, so it may require a longer course or change of medicines
