i am suffering from a skin black colour patch on my feet from 4 years dont known what exactly it is. its itchy ,rough, flaky and increasing.i had it when i was small in my feet for 7 years but get cured automatically but now it again happened but in different place. it stated from a shoe bite which get converted in to itchy patch.
Thank you for the question .you may apply antifungal creams like silk antifungal three times daily for one month. Keep the foot Chat Doctor.
