The problem the you are reporting could be a fungal infection of the skin like ringworm. It needs to be treated with proper antifungal tablets and creams FOR A PROLONGED DURATION to completely eliminate the infection from the skin. Most common cause of recurrence is premature cessation of treatment. Also your clothes have to be washed and sun-dried and family members need to be treated if anyone else also has it. However without proper examination and confirmation of the cause, treatment cannot be advised. Get an online consult privately with pictures or meet a dermatologist directly for a proper evaluation of the condition. Hope this was helpful.
