How To Cure Ringworm Formation On Left Arm?

HI DOC, I HAD RINGWORM OVER MY LEFT ARM FOR MORE YEAR NOW AND I THOUGHT IT WAS CURED AND LEFT A VERY WHITE SCAR BUT IT STARTED TO BE ITCHING AGAIN NOW. I ALSO TRIED A LOT OF FUNGAL OINTMENT FOR THE SCAR TO GO AWAY BUT STILL THE WHITE SPOT IS THERE. PLEASE GIVE ME ADVISE ON THE OINTMENT TO BE USED OR MEDICATION FOR IT TO BE CURED COMPLETELY. THANK YOU VERY MUCH FOR THE ATTENTION.

I AM 32 YEARS OLD FEMALE
