Posted by In this article, you will learn the theories of chronic pain, acute pains and ways of managing chronic pain, understand pain signals, and their implications for mental health — not exclusively about using nonsteroidal anti inflammatory drugs, but also with relaxation techniques, and other natural pain medicines.
Anatomy of Nerve Pain
As a result of these puzzling findings, in the early 1960s a new theory of pain was proposed to explain the widely acknowledged role of the mind and brain in the experience of pain in clinical practise. The gate control hypothesis of chronic pain was established first by Ronald Melzack and Patrick Wall.
The scientific beauty of this theory is that it gives a physiological basis for the complex phenomenon of pain, even while it accounts for things that are largely mental in character, such as pain itself and some of the psychological elements affecting it. This is accomplished by delving into the two primary subsystems that make up the nervous system:
The brain and spinal cord
Anatomy of the Brain and Spinal Cord (nerves outside of the brain and spinal cord, including branching nerves in the torso and extremities, as well as nerves in the lumbar spine region)
The gate control hypothesis postulates that the perception of pain is the result of a sophisticated interaction between these two systems, which handle pain signals in different ways. When an injury occurs, pain signals travel down the peripheral nervous system to the spinal cord and eventually the brain. So far, this is quite similar to what was outlined in the specificity hypothesis of pain.
According to the gate control hypothesis, however, the pain signals must first pass through “nerve gates” in the spinal cord, which open and close based on a variety of conditions before they can reach the brain (possibly including instructions coming down from the brain).
At times when the floodgates are “opening,” signals of pain “get through” with relative ease, resulting in excruciating discomfort. When the gates are shut, the brain is not receiving pain signals and the person may not feel any pain.
Although no one has yet figured out the specifics of this process or how to regulate it, the following ideas are offered to assist explain why different therapies are helpful and how to discover answers to persistent back pain.
The Periphery Nervous System
Various regions of the body are connected to the spinal cord by sensory nerves that relay information about sensations including pain, heat, and cold. It is believed that the bulk of pain signals are sent to the spinal cord by at least two distinct kinds of nerve fibres:
A-delta nerve fibres transmit 40 mph+ electrical signals to the spinal cord (“first” or “fast” pain).
C-fibres, which transmit electrical impulses to the spinal cord at a rate of about 3 miles per hour (“slow” or “continuous pain”)
The activation of the faster A-delta nerve fibres is followed by the activation of the slower C-fibres, which is an excellent example of the different functions that these nerve fibres provide. When various types of nerve fibres are stimulated, the brain receives conflicting signals about whether or not it should register pain.
The common practise of touching an injured elbow or head after a fall can help reduce the pain associated with the blow. Some of the pain signals conveyed by the A-delta and C-fibres are overridden by information about pressure and touch transmitted by other sensory nerve fibres that are even “faster” than the A-delta fibres.
Treatments like massage, heat/cold packs, transcutaneous nerve stimulation, and acupuncture are typically useful for relieving back pain because they target these different types of nerve fibres.
Specialized peripheral nerves carry information from the back’s nerve endings to the spinal cord and, from there, to the brain. Such transmissions are susceptible to interference from other signals in the ways discussed above. Some of these variations in nerve fibres explain why treatments like massage, heat, cold, TNS (transcutaneous nerve stimulation), and acupuncture can alter a pain message.
Similar considerations apply to aching backs. Multiple components in the back—muscles, ligaments, discs, vertebrae, and facet joints—have pain-sensing nerve terminals.
Specific peripheral nerves will send a pain signal to the spinal cord and the brain if one of these structures becomes irritated, inflamed, or mechanically dysfunctional. Other signals, generated by the aforementioned therapies, can silence these.
Chronic Pain: Opening and Closing the Pain Gates
We now know that pain signals can be quick or slow, follow a variety of neural routes, and be modulated by chemicals like endorphins in the brain stem, among other things. However, the human nervous system’s pain detection and response is more refined.
To activate or deactivate nerve gates in the spinal cord, the brain need only send signals down the cord.
Pain signals at the nerve gate in the spinal cord may be amplified by descending messages from the brain during times of anxiety or stress. Alternatively, “closing” impulses from the brain can prevent the nerve gate from opening, so blocking the pain signal before it reaches the brain.
Now we’ll take a look at some more triggers and mitigators of pain transmission in the spinal cord. These can be categorised essentially as sensory (body and actions), cognitive (mind), or affective (heart and soul), with, of course, a great deal of overlap in practise.
Some of the situations that might lead to an increase in pain are as follows:
- Sensory variables, such injury, inactivity, long-term narcotic use, poor body mechanics, and poor pacing of activities
- Mental elements, such as dwelling on one’s agony, lacking in any positive mental or emotional outlets, worrying about one’s discomfort, and so on and so forth.
- Emotional states including sadness, rage, fear, tension, annoyance, despair, and helplessness.
- Cognitive factors, such as increased activities, short-term use of pain medication, relaxation training, and meditation, can help close the pain gates and lessen suffering.
- Mental elements, such the patient’s outlook, coping strategies, and ability to divert attention away from the pain.
- Emotional elements, such as a proactive outlook, the ability to push through sadness, confidence that the pain is harmless, the ability to exercise autonomy over one’s life and chronic pain, and the ability to handle stress.
