Can you tell me the story of Amir Shakkar and how Sai Baba helped with his rheumatism?

Certainly. As detailed in Chapter 22, a man named Amir Shakkar was afflicted with severe rheumatism and sought a cure from Sai Baba. Instead of a conventional remedy, Baba instructed him to reside in the old, dilapidated Chavadi for nine months. The conditions were dreadful, with dampness, cold, and filth. However, Amir's true medicine was his unwavering faith in Baba's word. Despite the external hardships, this arrangement allowed him to have Baba's darshan frequently. This story shows that Baba's cure was rooted in faith and obedience rather than physical comfort.
