Can you narrate the story from Chapter 34 about the doctor from Malegaon and his nephew's illness?

Certainly. Chapter 34 of the Shri Sai Satcharitra recounts the story of a degree-holding doctor in Malegaon whose nephew suffered from a severe bone-cyst, also known as Hadyavarn. Despite the doctor's own expertise and the efforts of many other physicians and expert surgeons, all medical treatments, including surgery, proved futile. The young boy was in immense pain. Having exhausted all remedies, the family heard about Sai Baba of Shirdi. As a last resort, the parents traveled to Shirdi, prostrated before Baba, and explained their child's suffering. Sai Baba, the embodiment of compassion, reassured them, gave them Udi, and instructed them to apply it to the wound, telling them to be free from worry.
