What Causes Upper-Mid Back Pain?
Similar to Neck Pain and Headaches, the way we use our bodies has large impacts on how our bodies function.
The upper and middle back has many structures influencing it; these are predominantly to muscles and joints associated with:
Neck
Rib cage
Lower back
Shoulders
However, the posture the body holds can also be a result of biomechanics alterations originating from the hips, knees and feet.
Heart: strong pounding heartbeat, breathlessness, crushing chest pain
Lungs: wheezing, constant pains, breathlessness
Stomach: constant burning sensation/reflux particularly affected by food intake.
If you have these sorts of symptoms seeing your GP is highly advisable so that they do not develop or cause longer-term problems.
