Hello dear, The rash in your leg can be either due to dermatitis or fungal infection (Tinea) in that region. 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 or Miconazole to tackle the causative organism. 4. Topical antibiotics to prevent secondary bacterial infections. 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 undergarments and trousers, as it will cause sweating & predispose to fungal infections. Wishing you a Good Health. Take care.
