Neurosciences in the fight against chronic pain

Chronic pain can imply a significant loss in the quality of life for the person, being a condition that per se is an extra packaging affects the different areas in which the person operates, such as interpersonal relationships, academic performance, etc. Work represents an important cause of sick leave, impacting on finances, since the comprehensive treatment of chronic pain itself involves great costs, they can be even greater than those of other conditions that the patient presents.

Studies on pain and its genesis

Min Zuho (2018), in a study carried out at the University of Medicine in Toronto, Canada, stated that: “When doctors cannot find what causes pain, they believe that the patient is inventing”, in addition to the fact that many diseases with Those that are associated with chronic pain present modulation of symptoms by movement, so that the patient may be experiencing a lot of pain, however, when they reach the doctor, sometimes the pain can decrease or even disappear, thanks to movement, as happens with fibromyalgia. and ankylosing spondylitis.

Min Zuho conducted experiments with mice and rats, discovered that the frontal lobe of the brain is involved in the transmission of pain to the spine, stated: “When you have excessive anxiety, neurotransmitters are released that end up causing pain in the spine, it can begin to treat ordinary sensations as painful ”, he deduces that this may explain that emotional suffering physically causes pain, a person who is in great anguish may manifest pain in the chest in an intense way, for example.

Chronic pain and central sensitization (CS)

The International Association for the Study of Pain (IASP) describes it as an "unpleasant sensory and emotional experience associated with an actual or potential injury." It contributes to the transformation of sensory information into electrical impulses, often the painful sensation lasts beyond its cause. Chronic pain is that which is latent or persistent for more than three months.

The transmission routes can be sensitized in a way that causes pain to continue to occur, numerous experimental tests show that a painful stimulus of great intensity can be the cause of a series of functional and anatomical alterations of the central nervous system (CNS).

Another "invisible" disease: Chronic Pain

Have you been told that the physical pain you really experience is psychological because they couldn't detect its source? Pain is important and must be taken into account for its optimal management, in the case of chronic pain, pain symptoms are not a psychological issue only in most cases, when the patient experiences pain, neuroimaging tests show how it is modified the way in which peripheral sensory information is managed and processed.

In most long-lasting pain, central sensitization (CS) coexists, characterized by the presence of spontaneous or persistent pain, spread of the affected regions, and qualitative sensory disorders such as hyperalgesia and allodynia. Hyperalgesia is an amplified perception of pain before certain stimuli compared to a painful stimulus. Allodynia involves a pain response to certain stimuli that are not painful under normal conditions..

What memories of pain did you keep in your body? Chronic pain is a memory that lasts after an injury or without it, central sensitization (CS) can intensify pain, even when there is no tissue damage. The fact that pain is regulated by the brain does not mean that the pain is “psychological”, chronic pain is real and experienced by the patient, it represents a right (World Health Organization, 2017) and must be addressed.

Let us remember that the brain is like the great command center, what happens there has repercussions in somatic aspects. Many people have died suffering from terrible chronic pain, generally associated with other conditions, but not only with a terrible discomfort in their bodies, they were also immersed for a long time in confusion and suffering, which led them to irresponsible behaviors with their health and some of them they ended in suicide.

Depression is the psychopathology with the highest prevalence among the population of patients with chronic pain. Both conditions must be treated, since together they can incapacitate the person, even when the person is potentially capable of performing many activities successfully. When you experience pain intensely, it is natural to experience anxiety, sadness, irritability, anger and even aggressiveness (Fishman, 2000), it is common to feel confused, especially when experts still cannot offer you something that will completely relieve the pain.

If someone you appreciate or yourself has felt this way for a long time, I want to tell you that you do not have to try to carry this burden alone, recent research shows that it is possible to reduce the perception of pain by influencing psychological factors, if you have felt this way during For a long time, it may be time to seek psychological help, the lack of emotional regulation, pathological anxiety and too much stress can exacerbate the pain, working on the management of psychological aspects of your person can provide you with a better quality of life.

"Even though the world is full of suffering, it is also full of brave people who are overcoming it." Hellen keller

A separate condition: Chronic pain

There are various classifications of chronic pain, according to different clinical criteria. Chronic pain has comorbidity with many conditions that are also increasing globally, which is why the WHO (World Health Organization) has classified chronic pain as a disease in itself and its treatment represents a human right (2017); However, health is the responsibility of each individual, when seeking to improve the condition of life, it is necessary to do what is possible according to the faculties and to the extent of the available resources.

In clinical practice, we assess current sensory intensity and over time, as well as affective intensity, since they are correlated. For this reason, neurosciences show that in order to offer the patient a better quality of life, it is necessary to treat the body and the mind, since the coping strategies for pain that the patient uses can mark the course, the evolution and the pain maintenance.
