It is very common for ringworm to return, so please don't worry. For a localized recurrence, you can use an over-the-counter topical antifungal cream containing generic terbinafine, clotrimazole, or miconazole. Apply it to the affected area and slightly beyond the border twice daily for two to four weeks, even if symptoms disappear sooner. Keep the area clean and dry. However, because it has returned, I highly recommend consulting a healthcare provider. They can confirm the diagnosis and, if needed, prescribe a stronger topical treatment or an oral antifungal like terbinafine or itraconazole to ensure it is fully cleared.
