instruction: hi doctor I have ringworm on my arm I used daktarin and that did not work then I used cider vinegar and it has turned black should I be worried
output: hi I have read your query in detail and do understand your concern also I have viewed the attached pictures this is irritant dermatitis which has developed due to the use of vinegar it is very less probable that the fungal infection has been cured proper oral and topical medicine for one or two months is needed to cure your disease remember to wear loose cotton clothing especially when at home avoid hot humid climate keep the affected area dry and avoid synthetic innerwear if any other family members are affected they must also be adequately treated to prevent recurrence also get your blood sugar levels tested meanwhile you may apply antifungal cream such as clotrimazole twice daily over the lesions of ringworm revert back with the answers for the above questions to a dermatologist online
