Why was the Chavadi such a difficult place for Amir Shakkar to live in while he was being treated for rheumatism?

Chapter 22 provides a vivid and grim description of the Chavadi's conditions. It was an old, dilapidated building filled with lizards, house lizards, and poisonous scorpions. The text notes that lepers also stayed there and dogs ate leftovers on the premises. The ground was uneven, with seventeen knee-deep holes, and filled with garbage. Adding to the misery, Amir had to contend with rain from above, dampness from below, and a constant chaotic environment of wind and cold, which was especially difficult for someone suffering from rheumatism.
