"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 distinction between the two versions is that Palmer recorded in a major key - while Martin wrote the original in a minor key, making the song sound more ominous. The Palmer version was remixed with heavier guitars and drums for his 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. A cover version of the chorus also is part of the theme of the American syndicated series The Doctors.
