"The back is such a large and important part of the body, it's not unusual for it to develop aches and pains," Hascalovici explained. "While back pain can be characterized in many different ways, it can be convenient to classify it by where it shows up."

Neck pain: "Unfortunately common, neck pain can happen for quite a few different reasons. The neck can get sore from supporting an out-of-alignment head -- if you carry your head thrust forward, for example, hunch, or have 'text neck', you may notice soreness and difficulty turning your neck. Arthritis can happen, or the neck can get injured. It's also not uncommon to wake up with neck pain from unsupportive pillows, from sleeping on your stomach, or from tooth-grinding during the night, among other things."

Upper back pain: "The upper back, or thoracic spine, can suffer from musculoskeletal pain," Hascalovici said. "Discs can slip, strains can occur, and nerves can get pinched. Often, the causes of upper back pain can be traced back to being sedentary, having relatively poor posture or weakened muscles that let the spine tilt out of alignment. Upper back pain can affect the shoulders; shoulders may also hurt if you've been putting pressure on them unevenly while sleeping."

Lower back pain: "Only five vertebrae comprise the lower back, but those bones bear a lot of weight and pressure," Hascalovici said. "Herniated discs, muscle strains, nerve damage, and arthritis can all cause lower back pain. Doing heavy, repetitive labor, lifting heavy weights, toting a hefty bag around, or slumping don't help, either. For people with lower back pain, a medium-firm or firm mattress can sometimes yield some pain relief."

"Wherever pain shows up in the back, it can be frustrating," he continued. "The back is vulnerable to damage and to soreness caused by inflammation and arthritis; stress also contributes to back pain, since it often makes people clench their muscles." As a remedy, Hascalovici suggested "supplements, regular exercise, good posture, an anti-inflammatory diet, managing stress, and getting enough sleep all help to prevent and manage back pain."
