"The Carpal Tunnel of Love" was the first song to be heard off of the Fall Out Boy album, Infinity on High. It was originally leaked online by the band, and later given to iTunes as a digital download before Infinity on High was released. In addition, a web-exclusive video was released, but later saw televised airplay on Music Choice On-Demand.

The song was not a proper single, but was simply given out early by the band to give fans a taste of the album. The first proper single off of the album was "This Ain't a Scene, It's an Arms Race".
