"Bad Case of Loving You (Doctor, Doctor)" is a 1978 song written by Moon Martin and first recorded on his album Shots From a Cold Nightmare. A year later the song appeared on Robert Palmer's 1979 album Secrets and was a hit, reaching #14 on the U.S. Billboard Hot 100, #10 on the Cash Box Top 100, and #1 on the Canadian RPM chart in 1979. The main difference between Moon's version and the cover by Robert Palmer is that Palmer's version is in major key while Moon's in minor, making the song sound more ominous. It was remixed with heavier guitars and drums for Palmer's greatest hits collection Addictions: Volume 1. The song was nominated for Best Male Rock Vocal Performance at the 22nd Annual Grammy Awards.
The song begins with a stanza written in typical 8 bar blues structure & chord sequence, and then progresses to a 10 bar blues chorus. Other uses of mixing bar structure include "Bird Dog", recorded by The Everly Brothers and written by Felice and Boudleaux Bryant in 1957, which has a 12 bar blues stanza and an 8 bar blues chorus. "Bad Case of Loving You", however, is an example of mixing the rarer 10 bar blues structure in charted country compositions.
Mexican-American singer Tatiana recorded a Spanish-language cover version in 1994 for her album Un Alma Desnuda and was released as the second single from the album.
