What exactly is pain from a metabolic perspective?

Microcurrent and LED light therapy are non-pharmacological approaches to pain management that can be used to complement drug-based treatments within the WHO stepwise approach. Whilst microcurrent therapy stimulates cellular metabolism and improves blood circulation, LED light therapy uses specific wavelengths to influence cellular activity and achieve anti-inflammatory effects. Both therapies offer a low-side-effect alternative for pain relief and should be used as part of a comprehensive treatment plan in consultation with healthcare professionals.

Pain is a complex phenomenon that plays a central role in our daily lives. It serves as a warning signal for the body, indicating potential damage or injury. In this encyclopaedia article, we will examine the metabolic origins of pain and explore the different types of pain.

Pain can arise in various ways, and one important component is the metabolic aspect. Metabolism refers to the biochemical processes that take place in our cells to generate energy and maintain vital functions. It turns out that metabolic changes can play a key role in the development of pain.

Pain can be triggered by a range of factors, including inflammation, injuries, infections or diseases. These triggers lead to metabolic disturbances, which in turn release chemical signals in the body. Inflammatory processes, for example, release inflammatory mediators such as prostaglandins, cytokines and bradykinins, which stimulate pain receptors and send pain signals to the brain.

Another metabolic mechanism that can lead to pain is tissue acidification. During strenuous muscular activity, such as intensive exercise, lactic acid can accumulate in the muscles and lower the pH level of the tissue. This acidification can cause pain and muscle soreness.

There are various types of pain, which differ in their cause, course and characteristics. Acute pain is short-term pain caused by tissue damage, injuries or surgery. It serves as a warning signal and helps the body to protect itself from further damage.

Chronic pain, on the other hand, is long-lasting pain that can persist over a period of several months or even years. It can arise from conditions such as arthritis, fibromyalgia or back problems. Chronic pain often has a complex metabolic basis and may be attributable to structural or neurological changes in the body.

Neuropathic pain arises from damage to or malfunction of the nervous system. It can feel burning, stabbing or like an electric shock, and frequently occurs as a result of nerve damage, diabetes or inflammatory conditions. This type of pain is often perceived as particularly distressing, as it is frequently difficult to treat and can become chronic.

Visceral pain is pain originating from the internal organs, such as abdominal pain associated with gastrointestinal disorders or pain caused by cholecystitis. This pain can be dull and aching.

Pain management according to the WHO step-by-step approach

Pain management according to the WHO stepwise approach is a widely used concept for treating pain, developed by the World Health Organisation (WHO). It consists of a three-step approach that tailors pain management to the severity of the pain.

The first step of the WHO stepwise approach involves the use of non-opioid painkillers such as paracetamol or non-steroidal anti-inflammatory drugs (NSAIDs) to treat mild pain. These medicines have pain-relieving and anti-inflammatory effects, but their analgesic effect is limited.

If the pain persists or worsens despite treatment with non-opioid painkillers, the patient moves on to the second step. Here, weak opioids such as codeine or tramadol are used in combination with non-opioid painkillers. This combination provides improved pain relief and is suitable for moderate pain.

In the third stage of the WHO pain ladder, strong opioids such as morphine or fentanyl are used to treat severe and chronic pain. These opioids act on the central nervous system and can provide effective pain relief. Where necessary, they can be combined with non-opioid painkillers or adjuvant medicines such as antidepressants or anticonvulsants to optimise pain management.

The WHO pain relief ladder also emphasises the importance of adequate pain assessment and the individual tailoring of treatment. It suggests that the dose of medication and treatment intervals should be tailored to the patient’s needs. The aim is to achieve adequate pain relief whilst minimising the side effects of the medication.

However, the WHO stepwise approach does not only consider pharmacological therapy; it also emphasises the importance of non-pharmacological approaches such as physiotherapy, psychotherapeutic support and pain management interventions. These can be an effective complement to pharmacological therapy and improve pain relief.

Overall, the WHO stepwise approach offers a structured approach to pain management, enabling treatment to be tailored to individual needs and the severity of the pain. It serves as a guide for healthcare providers in decision-making and supports comprehensive and effective pain management.

Microcurrent and LED light therapy within the context of the WHO stepwise approach

Microcurrent and LED light therapy are two non-pharmacological approaches that can be used as part of pain management according to the WHO stepwise approach. Alongside pharmacological treatment, these therapies offer an alternative means of pain relief and can be used in combination with other stages of the ladder.

Microcurrent therapy is based on the application of weak electrical currents that target specific areas of the body. These currents can stimulate the body’s natural healing processes by improving cellular metabolism and promoting blood circulation. The targeted application of microcurrents can provide pain relief, particularly for muscle and joint pain as well as neuropathic pain.

LED light therapy, on the other hand, utilises specific wavelengths of light to stimulate cell activity and achieve anti-inflammatory effects. This is achieved through the use of LEDs (light-emitting diodes), which emit light within specific colour spectra. Different colours can have different effects; for example, blue light can have an anti-inflammatory effect, whilst red light promotes tissue regeneration. LED light therapy can be used for various types of pain, including muscle pain, joint pain and chronic pain.

Both microcurrent and LED light therapy offer non-invasive approaches to pain management with few side effects. They can be used as a complement to drug-based therapies, particularly in stages 1 and 2 of the WHO pain management ladder. Through the targeted application of microcurrents and light, individualised pain relief can be achieved, tailored to the patient’s needs.

It is important to note that microcurrent and LED light therapy should form part of a comprehensive treatment plan that also includes other non-pharmacological approaches and pharmacological interventions. The decision to use these therapies should be made in consultation with a healthcare professional to ensure safe and effective use.

Overall, microcurrent and LED light therapy offer innovative approaches to pain management based on the principles of biocybernetics and the regulation of cellular metabolism. By integrating these therapies into the WHO pain management ladder, it is possible to achieve personalised and holistic pain management, combining various treatment approaches to achieve optimal outcomes for patients experiencing pain.
