Who was the doctor from Malegaon mentioned in the story about the bone-cyst, and what was his specific problem?

The story in Chapter 34 of the Shri Sai Satcharitra speaks of a degree-holding doctor who lived in Malegaon, in the Nashik district. He was faced with a deeply distressing situation because his own nephew was suffering from a severe ailment, a bone-cyst known as Hadyavarn. Despite being a physician himself and having the help of other expert physician and surgeon friends, all their efforts, including native, foreign, and even surgical treatments, failed to cure the boy. This helplessness is what led the family to eventually seek out Sai Baba in Shirdi as a last resort.
