Suggest Treatment For Recurring Ring Worm Infection On Inner Legs

I have been facing thiss problem for the last three years. In summer time every year, i had ringworm in my inner leg areas . A dermatologist 3 years back prescribed me terebenafine tablets and clonate-f cream. After 1 months all of the rashes and fungal infections gone. But every years it comes backk again in summer time and again i had to take medicines. This years also i have been facing this problem and now i am using a kevon (ketoconazole 2%) lotion instead of clonate-f And taking terbenafine tabs. is there any way so that i can get rid of this fungal infections once and for all. I always keep my body clean and skin suurface healthy,, but then also every year ffungal infectiions occur in different parts off body.
