What were the specific physical problems Laxmichand was having, and what did Baba say that showed he knew about them?

According to Chapter 28, Laxmichand was suffering from two distinct physical issues that made him feel restless: intense hunger in his stomach and a sharp pain in his back. While Laxmichand was silently enduring this discomfort, Sai Baba, demonstrating his inner knowledge, spoke the following words: "Hunger has come, that's good. There should be medicine for back pain. Now the wind of khaja has blown; do the arati quickly." These words were a direct and clear expression of Laxmichand's exact condition. The Satcharitra, in Chapter 28, highlights this moment as an "Echo without sound," where Baba vocalized what was secretly in Laxmichand's mind, proving his inconceivable knowledge.
