Pain Management

Acute Pain

Acute pain is pain that appears abruptly and is most of the time of short duration, less than three months. It is the body's natural alarm, indicating that there might have been an injury or tissue damage. Acute pain may be temporary and minor or severe and chronic. It is generally a common effect of recovery when someone has been injured, undergone surgery or illness. Acute pain should be effectively managed, ensuring a patient's comfort and helping prevent it from becoming chronic.

Signs of Acute Pain

  • Abrupt onset: Acute pain comes abruptly, perhaps directly reacting to a definite event such as a cut, burn, or fracture.
  • Attributable to Injury or Surgery: There is a positive association between the pain and a simple to determine cause, i.e. a surgical incision, a sports-related injury, or a broken bone.
  • Physiological Signs: An increased heartbeat, elevated blood pressure and sweating may indicate the body's response to acute pain.

Effects of Acute Pain

  • Physiological Stress: Uncontrolled acute pain results in a physiological stress response, which may lead to an elevation in heart rate, blood pressure, and cortisol, hence inhibiting the healing process.
  • Loss of Function: The pain may restrict the movement of a person, deep breathing, or physical therapy following trauma or surgery and cause complications such as pneumonia.
  • Risk of Chronic Pain: Proper management of acute pain will prevent future nervous system alterations and make an individual more prone to developing chronic pain even when the initial injury has been repaired.

Chronic Pain

Chronic pain is unrelieved pain, which goes beyond normal healing time or, in some cases, exceeds three to six months. Contrary to acute pain that is the result of trauma, chronic pain is a disease. It may develop due to an old injury, an ongoing disease such as arthritis, or it may not be associated with any apparent cause. The disease may be disabling to a person's physical and mental well-being. In many cases, the effective treatment will include multidisciplinary intervention, such as using medications, physical therapy, and psychological assistance.

Signs of Chronic Pain

  • Long-term (Greater Than Three Months): The most distinctive symptom is a period of pain experienced over a significant duration, usually far beyond the initial injury or ailment.
  • Daily Life and Impaired Function: The pain is so bad that it can affect an individual's daily work, interaction with other people, and daily chores, causing considerable deterioration of their lives.
  • Psychological Symptoms: The constant pain is usually accompanied by psychological elements such as depression and anxiety, combined with a feeling of helplessness.

Effects of Chronic Pain

  • Physical and Psychological Distress: The pain might have numerous physical impacts such as energy loss, disordered sleep and impaired immune system. It also leaves a significant psychological effect, most times resulting in depression, anxiety and increased chances of suicide.
  • Decreased Movement: Because of pain, one can reduce the number of movements, resulting in muscle weakness, joint stiffness, and loss of mobility. This forms a vicious cycle of inactivity and more pain.
  • Social and Financial implications: This chronic pain may result in the loss of a job, financial problems and isolation. It may cause distress in intimate relationships, such as family and friends.

Neuropathic Pain

Neuropathic pain is a chronic pain caused by damage to the nerves themselves and not as a result of tissue damage. It has been termed as burning, shooting, stabbing, or tingling. This pain is caused by a dysfunctional nervous system that transmits pain signals to the brain even when an injury is not ongoing. Generally, it can be caused by diabetes, shingles, traumatic injuries, and multiple sclerosis. It is a pain that can be hard to treat using ordinary pain treatment medicines.

Signs of Neuropathic Pain

  • Abnormal Sensation: Numbness, tingling, or a so-called pins and needles feeling is the most frequent sign, as it commonly appears in the hands or feet.
  • Electric-Shock-Like Pain: They describe the pain as a sudden, sharp, shooting, or burning pain as though getting hit by an electric shock.
  • Allodynia is when an individual feels pain in response to something that should not cause pain (e.g., the light weight of the clothing or a light breeze).

Neuropathic Pain’s Effects

  • Physical and Psychological Distress: There is also a constant and uncontrollable presence of neuropathic pain. It may result in intense sleep disorders as well as exhaustion, anxiety, and depression.
  • Loss of Function: In extreme cases, the pain may cause functional impairments that reduce an individual's capability to move or do everyday activities, lowering their autonomy and quality of life.
  • Indifference to Treatment: Neuropathic pain is not influenced by most ordinary painkillers and therefore, alternative methods of treating this type of pain are needed, based on antidepressants, anti-convulsants, or other expert treatments.

Nociceptive pain

The most usual type of pain is nociceptive, which occurs due to stimulating pain receptors (nociceptors) in cases of actual or potential tissue damage. It is a normal and healthy way for the body to respond to injury as an indication that something is wrong. This pain is generally sharp, aching, or throbbing and occurs within the area of the injury. It is a common phenomenon in healing processes following a cut, burn or fracture, and common pain relievers can be used successfully.

Nociceptive Pain’s Signs

  • Related to Tissue Damage: This type of pain is physically associated with something broken, a physical wound, a surgical cut or even an injured ankle.
  • Localised Pain: This pain occurs locally and is easily identifiable to the patient.
  • Inflammation: This is usually associated with inflammation, which may include swelling, redness, pain, and warmth in the region of an injury.

Nociceptive Pain’s Effects

  • Protective Function: It is most sensitive to the protective effect. The pain alerts an individual to guard the injured part, which hinders further impairment and helps regain health.
  • Raised Heart Rate and blood pressure: Unchecked nociceptive pain may elicit a stress response, leading to an elevated heart rate and blood pressure, which may concern patients with underlying health conditions.
  • Loss of Function: The pain may restrict the movement of a person in the affected part, thereby complicating rehabilitation and the inability to resume normal modes of activity.
