Describe the medical crisis involving the doctor's nephew from Malegaon before his family turned to Sai Baba.

In Malegaon, a doctor with a degree found himself helpless when his young nephew developed a terrible ailment. As detailed in Chapter 34 of the Shri Sai Satcharitra, the disease was a bone-cyst, or 'Hadyavarn', which caused the boy immense pain and distress. Despite the father being a physician and enlisting the help of his expert physician and surgeon friends, no remedy worked. The family exhausted all options, trying both native and foreign treatments and even attempting surgery, but the malady showed no improvement. This complete failure of medical science left the family worried and desperate, paving the way for them to seek a spiritual solution.
