Mid-Back body stress
The chest and back areas may be strained by working in a hunched or twisted posture, e.g. bending over a sewing machine, doing woodwork, etc. Body stress may be caused by lifting heavy objects or by holding something up for a long time. Body stress may also occur as a painful spasm of the diaphragm muscle. Besides the mechanical causes mentioned above, the cause may be emotional tension, such as shock or anxiety, e.g. the typical “butterflies in the stomach” feeling. In addition the cause may be chemical, e.g. irritation from eating or drinking something spicy, acid or very cold. If there is body stress in the lower back, it may be referred into the muscles of the chest and upper back.
There may be a mild, nagging ache in the upper back between the shoulder blades, or possibly a persistent itching. The body stress may also manifest as a severe stabbing pain in this area, or in the chest. The pain is worsened by deep breathing. Body stress in the diaphragm muscle may result in indigestion or heartburn, or a feeling of breathlessness. It may also manifest as a constant feeling of hunger.
Body stress in the mid and upper back may have an impact on the nerve supply to various internal organs, such as heart, lungs, kidneys and bladder, and may interfere with normal function.
