Croton Oil an old psychiatric punishment for patients being held at a psychiatric hospital and is these days used for skin exfoliation. When Croton oil is topically applied it can give us an idea of the type of pain that originates at the dermis, the most superficial section of fascia in the human body. Croton Oil brings on a sharp pain experience coupled with a deep pain experience when applied to the skin. This fact enables us to imagine the pain pathways from fascia that relay the sharp and deep pain experiences. Deep pain does not necessarily mean a deep structure is in play or injured. Neither does sharp pain, often called an acute pain, mean that we have active damage and a nerve entrapment. Fascia can give rise to both deep and sharp pain experiences and thus should be a first port of call for people who have these experiences before their logical mind starts to relay to themselves that they have a nerve problem or a deep seated defect within their body.
Keeping on top of your fascial condition can be done with regular variety of movement (Tai Chi, yoga and Pilates) and with regular chiropractic care, in my humble opinion. don’t let it build up keep treatment simple and virtually painless and keep yourself well.
Tom Myers is well known to have disseminated knowledge of human anatomy whilst attempting to tie into his Rolfing practice the felt experience of having a human body. Myers has been touted as the Father of Fascia, quoted by a Canadian Masseur come science writer as being ‘over it'(1).
The architecture of the cell is remarkable for many reasons, the one of importance here is that when a cell is under tension from its environment as opposed to tension within its inner environment a change in genetic expression occurs. Yes! The nucleus of a cell alters the expression of its available genes from external tension placed upon the cell. If my body to some degree is a collection of cells that exist within the medium of my connective tissue. Then differences in connective tissue tensions have a genetic difference in how my cells within my body express the 23,000 (ish) genes I possess.
Allowing for markedly different function(s) to occur in adjacent areas of the body. Undoubtedly in my mind having an effect upon the mechanics of the area and the felt sense of the area and of the inner experience of the area; not to mention a different physiology of the area. A different genetic expression may give rise to a strength, or a vulnerability, altering ones health.
Is the falling rate of male fertility in modern society a result of immune system dysfunction? eg leukocytospermia. The dysfunction of white blood cells has been linked to MMP signalling proteins which also interact with c fibres of the nervous system (a route to give a pain signal). To summarise genetic expression, immune function and pain levels are all linked by science to connective tissue tension (aka fascia).
Are the rising levels of immune dysfunction (demonstrated by an over reliance upon antibiotics), the rise in autoimmunity disease rates and the rise in medically unexplained symptoms all a function of a change in the tensions placed upon our body tissues, because we just do not move as much as we did?
Fascia is one view of the body and in itself is not representative of the entire conglomerate of the human body and tells us nothing of the human (interoceptive) experience of having a body. A professional body worker (dancer yogi Qi Gong instructor included) would be well advised to have an adaptable view of the human body and not become any one tissue centric about their approach. After all as a teacher, instructor, therapist, chiropractor, osteopath or physiotherapist the outcome of a patient is not a function of how right you are!
Keep going science you have a long way from which to ‘catch up’!

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. (Fascia information above was collected from JBMT 2015 No.19). (Picture above from ‘stroll under the skin’ by Guimberteau)
The classic example of somebody having a restriction in their flexibility and they feel it at the back of the legs is thought to mean tight hamstrings. Yet in a fascial model of the body the TFL muscle is actually under about twice the strain that the hamstring muscles are under during a straight leg raise. The most obvious place to consider changing would be the side of the leg in tight hamstrings and not the back of the leg where it is felt! The fascial connections of the thigh are complex and numerous; for example in clinical practice I have ‘worked’ on the adductor muscle of the lesser affected leg and gained 20-25 degrees of extra flexibility in a straight leg raise of the more affected leg.
Having the view that my problem is where I feel it is a difficult concept for most to let go of. Sometimes where you feel it does not need to be changed. Where you don’t feel it does! Having an in depth knowledge of anatomy and understanding human movement and how tissues interact within the human body is essential to truly get to the root of a musculoskeletal problem.
Training such as in a Chiropractic degree (undergraduate Masters) is ideal to start to see the root causes of a problem within the human body. When the human body is not able to change in a certain place, the body compensates and thus moves the symptom, yet the root cause is still the same; there is just a longer more complex chain of events that exist once a compensation occurs. Addressing the fascia before any adjustments is my strategy in clinical treatment. This way I am able to work through the layers of compensation until I find the root cause. Step one for you with tight hamstrings is to come to terms that the root cause is most likely (if you’ve had the problem for more than 5 days) somewhere else (in my opinion) than the back of your leg. Psychologically speaking if you keep on putting your problem to the back of your legs you will in fact keep a problem at the back of your legs! When seeking help from a Chiropractor it can be useful to look up the conditions that have evidence behind them.
