Your back, spine, and torso, in general, are the sections of your body that hold you together, making them propense to injuries or ailments due to how often they are used. You need your back for most of your daily activities, and it’s imperative that you keep it healthy making sure that it is constantly performing the way it should.
Because your back is such an important and massive section of your body, the pain can manifest itself in many different ways. You also have to consider that many nerves run through your spine, and therefore, a problem with your spine could result in having pain in some other parts of your body — that we might think are unrelated — that are connected through the nerve system, giving you the sensation of feeling pain in those other places.
