You’re dehydrated

The bones of your spine have discs between them, each partly made up of a jelly-like substance that is 90 percent water. Your body needs a steady stream of fluid coming in to help keep that cushioning intact, according to the Cleveland Clinic Center for Spine Health. When your body lacks hydration, those discs become flatter and less cushiony, which can lead to pain. A good way to know if you’re drinking enough to water is to look in the toilet. Your urine should be clear or light yellow; if it’s dark yellow, grab some H20.
