What medical treatments were tried for the boy's bone-cyst before the family turned to Sai Baba's Udi?

According to Chapter 34, a comprehensive but ultimately unsuccessful range of medical interventions was attempted for the boy's bone-cyst. The boy's own uncle was a degree-holding doctor, and he, along with his physician friends, tried various treatments. The text explicitly states that expert and intelligent surgeons also became exhausted and felt helpless. Furthermore, both native and foreign treatments were tried, and even surgery was attempted. It was only after all these efforts were exhausted and the disease showed no improvement that the family decided to seek a spiritual remedy from Sai Baba.
