Talk to Dermatologist on Fungal Allergy

I have fungal allergy on my legs. I have tried many doctors who gave me different medications but the problem is that after applying and eating medicine for some days the disease looks like it is gone but even if I keep eating medicine and applying tubes/creams the disease starts increasing again. Its been 1.5 year and the disease is still not cured.I have tried different creams/tubes after consulting the doctors including Kennacomb, Lotricort,Travocort, Tineacort, Lamisil etc and many tablets and capsuls including Kestine, Fungone etc.
