I hurt my thumb while playing football with a friend. He threw me what is known as a bullet or fast spiral throw, and I felt instant pain in my left thumb. He said it was probably a jam, so I iced it immediately for 4 days straight. The pain went away, but not all of it. It has been 4 weeks, and it still feels bruised in certain parts of my thumb, mostly bothers me if I clap with both of my hands, espeically on the thumb side. SHould I got get it checked out/
