Mid back pain can also be associated with what we call 'viscero-somatic' pain. Firstly, to explain the difference between somatic and visceral pain:
With respect to the visceral pain, what can happen is that it can 'refer' pain to otherwise normal parts of the soma (musculo-skeletal tissues) as the brain gets confused as to where the pain is coming from. This explains why you can get mid-back pain from an underlying intestinal or stomach problem or, indeed, jaw and shoulder pain when you are having problems with your heart.
Specifically, the reason for this 'referral' of visceral pain is the lack of dedicated sensory pathways in the brain for information concerning the internal organs. The sensory neurons or nerves that take information from the viscera (internal organs) converge with the sensory neurons which take information from the soma within the brain. The brain then interprets the signals originating from the viscera as coming from the muscles and skin. This is known as a viscero-somatic reflex.
The reason this is of interest to the Osteopath is because it is important to differentiate between true musculo-skeletal pain and viscero-somatic pain. In the case of a patient presenting with viscero-somatic pain, it is key to refer the patient to the appropriate healthcare professional to have the underlying viscera (internal organ) examined and treated. Only once this is achieved will the patient recover adequately and the musculo-skeletal pain reduce or disappear.
Whether the pain is musculo-skeletal or viscero-somatic Osteopathic treatment can help to ease the symptoms using a combination of soft-tissue treatment and joint articulation, manipulation and stretching. Acupuncture and cranial osteopathic treatments may also be used as appropriate with exercises and advice given at the end of the treatment(s).
NB: Patients with a fever, breathing difficulties or a severe cough with frontal chest pain should consult their GP
