Why was staying in the Chavadi so difficult for Amir? What were the conditions like?

The Chavadi was an extremely challenging place for anyone, let alone someone with rheumatism. Chapter 22 describes it as an old, dilapidated building filled with lizards and poisonous scorpions. The conditions were unhygienic, with lepers staying there and garbage piled in the back. The text highlights seventeen knee-deep holes, constant dampness from rain and the ground, and a chaotic environment of wind and cold. For Amir, whose joints were seized by his illness, these external conditions were completely contrary to healing. It was a true test of endurance and faith, described as a "pilgrimage of a lifetime."
