Check for the brand of medicines that you are using. Cheaper brands with inferior molecules do not work especially in an era of difficult fungal infections. ​​Fungal infection is becoming an increasing problem due to rampant usage of antifungals. Please see a dermatologist as some extra medications are coprescribed many a times to treat. I​​f needed a simple skin test can also be done. Till then use only OTC anti-allergic medications to control itching. Personal hygiene should be good. Wear loos​​e fitting clothes. Dr MK Agarwala
