Unfortunately they can start as a migraine or really bad headache that you take a bunch of over the counter (OTC) medications for and the don't work and you keep taking more and the headache doesn't get better and eventually you get a rebound headache because your body needs the medication.
Misty Mountain Hop. Misty Mountain Hop is a song from English rock band Led Zeppelin's untitled fourth album, released in 1971. In the United States and Australia it was the B-side of the Black Dog single, but still received considerable FM radio airplay.
That LP, released in the late summer of 1960, barely sold at all, despite the presence of Dave Fisher's Big Rock Candy Mountain.. A similar fate befell the single pulled from the album, Santiano b/w Michael, Row the Boat Ashore, and that seemed to be the end of the story.
