Hello, Welcome to HCM, As your history is suggesting me that you are having fungal infection for which you are taking oral antifungal drug like terbinfine and applying antifungal cream like candid cream over the pubic area. As your symptoms are not coming down even after one month of treatment, you need physical examination to confirm the diagnosis and then we can think of trying other antifungal drugs, which are effective against the funfal infection. I would suggest you to consult your dermatologist for further evaluation and treatment. Thank you.
