Ringworm that lasts for a year usually means the infection is not fully cleared, or it keeps getting reactivated. This can happen when treatment is stopped too early, cream is not applied long enough, the infection has spread to nearby areas, or there is constant sweating, tight clothing, or repeated use of steroid-mixed creams that temporarily reduce itching but allow the fungus to persist underneath. Sometimes the diagnosis also needs to be reassessed because chronic itching may overlap with other skin conditions. KZ cream can help in mild cases, but stubborn or long-standing ringworm often needs a more structured plan, sometimes including a different antifungal cream, longer duration treatment, and in some cases oral antifungal medicines prescribed by a doctor. Hygiene also plays a big role, like keeping the area dry, changing clothes regularly, avoiding sharing towels, and washing clothes in hot water if possible. Since your symptoms have been present for such a long time, it is important to get a dermatology review again. You may need an adjustment in treatment strength or duration to fully clear the infection and prevent recurrence.
