Can you tell me about the doctor from Malegaon whose nephew was suffering from a bone disease?

Chapter 34 of the Shri Sai Satcharitra narrates the story of a degree-holding doctor from Malegaon whose nephew suffered from a terrible ailment. The disease was a bone-cyst, or Hadyavarn, which proved incurable by any medical means. The doctor himself, along with his physician friends and expert surgeons, tried various native and foreign treatments and even surgery, but all efforts were exhausted and they felt helpless. As a last resort, after hearing of the famous saint in Shirdi, the boy's parents traveled to meet Sai Baba. They pleaded with him, and Sai Baba, the embodiment of compassion, reassured them and gave them Udi to apply to the wound, which the chapter explains completely uprooted the pain.
