Describe the medical condition of the nephew from Malegaon and the efforts made to cure him before his family sought Sai Baba's help.

As detailed in Chapter 34, the nephew of a degree-holding doctor in Malegaon suffered from a bone-cyst, referred to as Hadyavarn. The text describes this as a most difficult and extraordinary malady. The boy's uncle, being a physician himself, along with his physician friends and even expert surgeons, attempted various treatments. The chapter notes that all native and foreign treatments were tried, and even surgery was attempted, but every effort was exhausted without success. The young nephew was left in great pain and distress, and the medical professionals felt helpless against the incurable disease.
