Hello dear, The symptoms as mentioned in your post suggest that you might be having fungal infection. Repeated infections can be attributed to poor hygiene, decreased immune status of body or systemic disease like Diabetes. Management includes: 1. Keeping the area dry & avoid too much exposure to water or sweat formation. 2. Antihistamine preparations like cetirizine to reduce the itching sensation & provide symptomatic relief. 3. Application of topical antifungal cream like Clotrimazole to tackle the causative organism. 4. Topical steroids & antibiotics can also be used to prevent secondary bacterial infection. If symptoms still persist or aggravate further, then it will be better to consult a Dermatologist & get a proper examination done to find out the actual cause. So that appropriate management steps could be taken. Also avoid wearing tight clothes...as it will cause sweating & predispose to further infections. Wishing you a Good Health. Take care.
