16. Regular follow-ups are essential to monitor progress and manage side effects.
17. Physical therapy can help maintain muscle strength and mobility.
18. Protective footwear can prevent foot injuries in patients with nerve damage.
19. Surgery may be necessary to correct deformities and restore function.
20. Psychological support is crucial for patients dealing with stigma and isolation.
