Shoulder Pain

Your shoulder is very flexible, but it's also fragile. Pain in your shoulder can result from one of number of causes. An irritated nerve in your neck, repeated overuse, or an injury, can cause inflammation and stiffness and make everyday activities painful.
Low Back Pain

Your low back is a vulnerable area, constanly under the strain of supporting your upper body. Poor posture, injuries, wear and tear, hereditary weakness, or excess weight can cause a variety of painful low back problems.

Pain in the Neck
Your neck protects your spinal cord and spinal nerves, while supporting and balancing the weight of your head. Poor posture, wear and tear, injury, stress and tension can strain or damage vital parts of your neck.
A healthy neck is aligned in a natural curve at the top of your spine. Damage to your neck's natural curve can cause painful problems.
