Thanks for the query. Kindly meet a Dermatologist to decide if it's a corn or wart as its easy to get confused. Once the diagnosis is confirmed, there are multiple treatment options. Your Dermatologist will explain the advantage and disadvantage of each option offered. Based on the patient feasibility, any treatment option can be considered and followed. Maintenance treatment is needed. Option include simple excision, paring, cryotherapy, topical. Hope it helps. Dr MK Agarwala Dermatologist New Delhi
