Using numbing spray for feet during a pedicure to mask toenail fungus is not recommended. Numbing sprays may temporarily alleviate pain or discomfort, but they do not treat or eliminate toenail fungus. Toenail fungus requires specific antifungal treatments, which may include oral medications, topical antifungal creams, medicated nail lacquers, or in severe cases, surgical interventions. It is important to address toenail fungus promptly to prevent its spread to other nails or individuals. If you suspect toenail fungus, it is advisable to consult with a healthcare professional, such as a dermatologist or podiatrist, who can accurately diagnose the condition and recommend appropriate treatment options. Proper hygiene, regular nail care, and avoiding shared footwear or nail care tools are also important for managing toenail fungus effectively.
