Good Morning..Ringworm may sometimes be a difficult problem to treat..The medicines which you are using are appropriate but the dosage and duration of treatment is also very important..Local hygiene measures to minimise sweating and simultaneous treatment of other family members who have ringworm are also important to prevent recurrence of the infection.. Followup with your Dermatologist if the problem persists as he/she might need to change the medicines..Also anti-itch tablets will help in giving symptomatic relief..Hope this helps..Warm regards Dr. Vivek Shah,Consultant  Dermatologist, Sujay Hospital, Juhu & Criticare Hospital, Andheri East
