Hello,
Such itchy rash can be due to fungal or yeast infection. Most cases respond to
over-the-
counter products, which contain any of several basic ingredients: miconazole, tolnaftate, terbinafine, ketaconazole and clotrimazole. You can consult a pharmacist and get any cream or lotion containing these ingredients.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided.
