The *Neijing* (Inner Canon) states that dampness injures the flesh. This is because the Spleen governs the muscles, and the muscles dislike dampness. Before various sores heal, if they are exposed to water or dampness, water-toxin will manifest causing swelling, severe pain, and continuous pus discharge. This constitutes dampness injuring the muscles. The treatment should involve applying external medicines to drain the water completely, allowing the muscles to return to a warm and balanced state, thereby healing the sore.
