Why did the family of the boy with the bone-cyst decide to go to Shirdi after trying everything else?

According to Chapter 34, the family turned to Sai Baba as a last resort. After all medical treatments, including those from expert physicians and surgeons, had failed to cure the boy's bone-cyst, the family felt helpless. Relatives initially suggested worshiping deities, but that also brought no relief. Eventually, they heard about a famous Avaliya, or saint, in Shirdi named Sai Maharaj. It was said that he could heal diseases with just his sight and that his Udi could make even incurable diseases perish. Believing this was their last hope, they decided to go and bow at his feet to see if this calamity could be averted.
