i have a fungus on my ankle. my dr did a biopsy so we know what it is.. i have used a topical cream - it went away - but continues to come back now and again (particularly after hot exercise - like yoga are when there is rubbing on the area from a boot etc- like xcountry skiing) will this ALWAYS be the case - will it never go away or totally be cleared up and is there anything else i can take/do to eradicate it completely? thx
