One of the early things a boy going through puberty might notice is changing and doing it quickly. Boys can grow wider shoulders, get taller, and build more muscles, and their hands, arms, feet, and legs may grow faster than the rest of their body, which can make them feel awkward. The body will eventually catch up. Growing a lot in a short period of time is called a growth spurt; some boys have a growth spurt early in puberty, while others have it later. Growth spurts can make a boy feel discomfort because the muscles don't grow as fast as a boy's bones. Boys can ease the discomfort by using a heating pad.
