Do you spend all day sitting at work and your evenings looking down at a smartphone? Before you realize it, your hunched shoulders, upper back, and the area around your scapula can feel tight and tingling, while your lower back aches enough to make you sigh.

Have you ever felt a sudden heaviness and stiffness right in the middle of your back while sitting at your computer all day or looking down at your smartphone? It feels as suffocating as carrying a heavy stone, and when it is hard even to lift your arms, you may wonder what you did wrong and feel downhearted. That stiffness may not be just ordinary muscle pain.
