What if I told you... 🙂⠀
⠀
Chronic (back) pain is not about mechanical problems, like a vertebra out of alignment, slipped disc etc.⠀
⠀
Pain is a complex, multi-factoral experience.⠀
⠀
Chronic back pain can be influenced by the following:⠀
-Psychological factors (depression, anxiety, stress, fear avoidance, illness beliefs)⠀
⠀
-Lifestyle factors (sedentary lifestyle, poor general health, poor sleeping patterns)⠀
⠀
-Social factors (job dissatisfaction and unwholesome work relationships, hypervigilance and over-concern from family)⠀
⠀
And that can create central sensitization (a bit controversial term), which is in fact a hypersensitive nervous system.⠀
Here a better explanation:⠀
"According to Woolf (2011), CS is ‘operationally defined as an amplification of neural signaling within the central nervous⠀
system (CNS) that elicits pain hypersensitivity’.⠀
⠀
CS is a broad concept reflecting not only spinal cord sensitization⠀
but also enhanced activity of pain descending facilitation pathways (Meeus and Nijs, 2007; Staud et al., 2007), loss of descending antinociceptive mechanisms (Meeus et al., 2008), overactivity in the pain neuromatrix (Seifert and Maihöfner, 2009) and long-term potentiation of neuronal synapsis in the⠀
anterior cingulate cortex (Zhuo, 2007).⠀
⠀
Wind-up, activation of collateral synapses, apoptosis of gABAergic⠀
inhibitory interneurons, sprouting of Aβ-fibres in lamina II or glial activation are also important functional changes observed in the CNS with CS (Woolf, 2011)."⠀

What do you think of this?⠀

Btw if you want to learn more about central sensitization, make sure to watch the new pain science course on Trustme-Ed by Niamh Moloney and Martin Rabey. Good stuff in there. 🙂👍
