Can you describe the specific medical case from Malegaon discussed in Chapter 34 and explain why it was considered a last resort to visit Sai Baba?

Chapter 34 recounts the story of a doctor's nephew from Malegaon who was afflicted with a severe bone-cyst, referred to as Hadyavarn. This ailment proved to be extraordinarily difficult, resisting all forms of treatment. The boy's uncle, himself a degree-holding doctor, along with his physician friends and expert surgeons, tried numerous native and foreign remedies, including surgery, but all their efforts were exhausted without success. The young boy was in constant pain and distress. As this chapter explains, it was only after all medical options failed and the disease showed no signs of subsiding that the family, in desperation, heard about the great saint Sai Baba of Shirdi. Visiting him was considered a final resort, a leap of faith taken when all conventional science and medicine had proven helpless.
