Yes, you can apply sodium fusidate 2% cream to the healing nail bed. After 10 days of oral antibiotics and pain relievers, transitioning to a topical antibiotic cream is a safe and effective way to keep the wound moist, prevent localized infection, and support tissue healing. Before applying, gently clean the area with clean water or sterile saline and pat it dry. Apply a thin layer of the cream and cover it with a fresh, dry dressing. If you observe any warning signs like worsening redness, swelling, throbbing pain, or pus, please consult your doctor. Otherwise, this is a safe next step in your recovery.
