The connection between the tissues of the human body bring all body components together on the inside. This connection is known as fascia. Sensory nerves (pain fibres) are densely packed into the superficial fascial layer. This superficial layer lies between the dermis and the deeper fascia. One could paraphrase that the underside of the skin and the top side of the skin are both well innervated by nerves; with the underside being more densely packed with sensory nerves (pain receptors). Whilst the outside of the skin has a greater variety of specialised nerves.
The way the superficial fascia is innervated confirms the idea of Andrew Taylor Still (Father of traditional Osteopathy) that the fascia of the body is a ‘sensory organ’. More recently Helene Langevin wrote about ‘a body wide signalling network’. How information is relayed to the brain, about the body. Udup also showed an interaction between the endocrine system and fascia in his research on hormones and yoga. The human brain, seems to me, to be calculating the movement of your body based upon sensory information from fascial tissue. Thus the condition of the fascia in your body can aid or hinder how you move (proprioception), how you feel and what hormones are being produced.
If you have an inefficient (relative to your most efficient) body you might experience delayed onset muscle soreness (DOMS). Called ‘muscle soreness’ yet it is accepted that the soreness is in fact from fascial tissue. Soreness from within your fascia can mean abnormal loading and conflicting sensory motor signals are occuring within your nervous system affecting your proprioception. Abnormal loading of fascia can lead to pain of a variety of intensities. Making identifying what you are doing to bring on the DOMS or pain difficult to pin point. Adversely loaded fascial tissue can give rise to what is traditionally thought of as ‘nerve pain’ or nerve root pain. As well as other types of pain.
Next time you are thinking you have a stubborn old injury, nerve issue, strain or sprain, perhaps you need your fascia attended to? This is why with fascia first chiropractic fascia is included along with your other body tissues as a potential source of pain and discomfort.
