When your head hits a wall and swells, it is often referred to as a "hematoma" or more specifically a "contusion." This occurs when blood vessels are damaged, leading to bleeding and swelling in the surrounding tissue. In common terms, it might also be called a "bump" on the head. If symptoms are severe or persistent, it's important to seek medical attention.
