Patients with white lumps on the soles of their feet and painful walking can be treated in several ways: First, if the pain is caused by corns forming on the plantar pressure areas, you need to wear soft-soled shoes and soak your feet in hot water to soften them, after which you can trim them with a razor blade and apply corns cream, salicylic acid fire cotton glue, or use laser treatment. If conservative treatment is not effective, surgery can be used to remove. Secondly, if the callus is formed by long-term skin pressure and friction, causing local pain, you should wear hard-soled, soft-padded shoes, soak and trim, and use salicylic acid phenol paste to apply externally. If conservative treatment is not effective, surgical treatment is also needed. Active treatment by the above methods can bring about rapid relief of clinical symptoms, but some patients’ symptoms are prone to recurrence, so attention should be paid to usual protection and try to wear loose shoes to avoid local pressure.
