Why does my back hurt?


assistant
There are several reason why your back might hurt.  Generally, the problem starts not in your back but in a connected muscle group. To assess the problem, start with your feet and work your way up to your shoulders and neck.   If your shoulders and/or neck are tight, that will affect your back muscles.  Also, consider your shoes, your weight, the strength of your knees, and your core strength.
