* Burns: He suffers burns on his arms, face, and back. These are described as "bad burns" and "nasty" in the book.
* Smoke Inhalation: The severity of this is not explicitly stated, but he is shown to be coughing and struggling to breathe after the fire.
* Possible Concussion: He is knocked unconscious by the fire and takes time to recover. It's implied he may have suffered a concussion, but this is not confirmed in the book.
It's important to note that the extent of Ponyboy's injuries is not described in detail. The focus of the story is on the emotional impact of the fire and its consequences for the characters, rather than a detailed medical description of his wounds.
