We may have cancer and feel good, or be submitted to substantial disability and suffering without doctors finding any evidence of disease. Medicine gives no acceptable answers to the last situation and arbitrarily appeals to denying the reality of suffering, making the calvary of patients even more unbearable. This blog tries to contribute with the knowledge of the neuronal network, giving a little light to this confusing section of pathology.

Pain and inaction


The function of perception is to focus, care for a theoretical or real content and propose an interaction. Perception is a proposition with a variable load of motivation to act in a certain way, with a purpose and significance (positive or negative).

Pain is a perception whose purpose is to force the individual to act defensively. If we contact with a noxious foreign agent or status, pain will force us to avoid it, to flee-fight. If the noxious agent or state is internal, pain pushes us to inaction, to suspend the planned activities.

Standing, walking, bending ... are actions that the individual requests to obtain purposes. The brain knows the intention, the desire of the individual and selects its proposal. If the individual's application doesn’t show any threat (real or theoretical) to physical integrity, the brain activates silent motor programs perceptively. We get up, we bend, we take things ... with nothing relevant in the execution. The individual’s request has received the brain’s approval. The action has been painless because the brain’s evaluative action has approved it without hesitation.

If there is a vulnerability assessment (theoretical or real) in an area of an individual's request for a given action-purpose, it can generate a cerebral fear of damage. The brain doesn’t approve it and perceptively projects fear (fear of injury) and pain (deterrent penalty) while it selects a defensive motor program with inadequate muscles. The individual perceives both cerebral projections: fear and pain, and proves that the action is inadequate, slow, painful, stiff ...

Pain has fulfilled its deterrent function. It has forced inaction. If despite the pain the individual decides to continue with its purpose, the pain will increase until it achieves its goal: to compel surrender. It stops acting in the individual’s desired direction and contributes to the inactivity of an area that is considered vulnerable.

Cerebral action of selecting and projecting pain perception in an area also contains a forecast of which actions of the individual are required to turn off the pain. If the brain requires a drug, there will be no relief until the individual performs the action to take it. If the brain requires relaxation, the individual must do it in order to make the pain go away.

Taking an analgesic is an action, something more than introducing a single molecule in the body. The brain calls for actions. Food doesn’t take away the hunger with molecules. Eating is an action that the brain requires by the projection of hunger perception. If you obey, the brain turns off the appetite.

We mustn’t always accept the brain’s proposals. We must learn to value them as rational and sensible or otherwise and act accordingly.

If the brain asks for inaction by an alarmist assessment, we must defend with arguments our willingness to act and get the brain to mute the perception of fear of harm (pain) and to organize the motor gesture with economic and quiet programs.

- Don’t move, don’t do it!

- Come on!
