What sequence of events led the family from Malegaon to finally seek out Sai Baba in Shirdi?

Chapter 34 details a clear sequence of escalating desperation. First, the family tried every available medical option for the young boy's painful bone-cyst. His uncle, a doctor, and other expert physicians and surgeons tried numerous treatments, including surgery, but all failed. The chapter states that 'all native and foreign treatments were tried; all efforts were exhausted.' Second, after the complete failure of medical science, relatives suggested a spiritual path, advising them to worship deities. This also did not seem to help. Finally, having exhausted both medical and traditional religious avenues, 'word reached their ears of a famous Avaliya (saint) living in Shirdi.' Hearing that Sai Maharaj could heal diseases by his mere sight and that his Udi could cure the incurable, they decided to make the journey as a last resort to avert the calamity.
