Describe the medical condition and the failed treatments that led the family in Chapter 34 to seek Sai Baba's help.

The ailment detailed in Chapter 34 was a bone-cyst, referred to in the text as Hadyavarn. It was described as a most difficult, extraordinary, and painful malady afflicting the young nephew of a degree-holding doctor from Malegaon. The boy's uncle, being a physician himself, along with other expert and intelligent surgeons, attempted various treatments. According to the chapter, they exhausted all options, trying both native and foreign remedies, and even performed surgery, but nothing succeeded in alleviating the boy's suffering. It was only after these extensive medical efforts proved completely futile that the desperate relatives, having heard of a famous Avaliya in Shirdi, decided to seek the divine intervention of Sai Baba as their final hope, which is the primary focus of the story in Chapter 34.
