Pain management

Acute pain starts quickly and is generally short-lived. Chronic pain is more persistent and usually lasts beyond the normal time for healing.

Pain management is important to maintain a reasonable quality of life, as the effects of chronic pain include:

• Faster heart rate and higher blood pressure
• Potential mental health disorders g. anxiety and depression
• Increased stress, fatigue and tension
• Gastrointestinal issues.

Early detection of pain and appropriate management are important as otherwise the person may adopt negative ways to cope with the pain. Some of the more frequent causes for pain following a brain injury are:

• Headaches and migraines
• Neck and shoulder pain (after traumatic brain injuries)
• Abscess and skin sores
• Cervical or spine injuries
• Heterotopic ossification (bony overgrowth)
• Kidney stones and bladder infections
• Fractures
• Spasticity
• Constipation.

Chronic pain can lead to depression, anger and anxiety disorders as sufferers may have many other negative events and stressors to deal with, such as losing their jobs, experiencing financial hardship and having increased stress upon their families. With chronic pain, people may believe the pain is increasing even though there is no medical evidence for this. In these cases other factors are at play including:

• Emotional functioning
• Past learning experiences
• The way others respond to the person’s behaviour.

Sleep and appetite disturbances intensify the disability that results from chronic pain. As time goes by, the person may become depressed and preoccupied with normal changes in bodily functioning and may worry about experiencing new illnesses.

The individual can develop a tendency to view all activities in terms of how much pain will be experienced. This can lead to a cycle of helplessness and despair, often accompanied by anger toward professionals who never seem to be able to cure the pain. In turn, professionals lose patience with the person with persistent pain who appears to have limited medical justification for these complaints.

Pain management strategies are usually based on one ultimate and constant objective-the reduction of pain, not its total elimination. If the person experiencing the pain and all of the professionals who treat the individual do not make this the goal, frustration will grow, resulting in failure to coordinate treatment efforts in a successful manner.

Research has shown that having realistic, helpful thoughts is an important part of pain management. Cognitive behavioural psychologists help chronic pain sufferers to change their thoughts about their pain, its effects, and other sources of stress.

One approach views pain as a learned behaviour and is done by a psychologist or neuropsychologist. Other approaches help the person to identify inappropriate and unhealthy beliefs about pain and provide strategies to deal more effectively with pain behaviour. Techniques may include relaxation training, hypnosis, stress management, attention-diversion strategies and biofeedback.

Pain management in brain injury is often difficult as medications may work against recovery. Many painkillers work against the re-emergence of the person’s mental and physical systems. Later, narcotics are a problem because of their potential for substance abuse and their negative side effect on the ability to think clearly.

Non-steroidal anti-inflammatory drugs (NSAIDs) which include asprin, ibuprofen (Nurofen), Voltaren, and other COX-2 inhibitors are appropriate for musculoskeletal pain. However, they can increase the risk of serious gastrointestinal complications (including ulcers) and may increase cardiovascular events in some people, so check with your doctors before taking them.

Antidepressants can be effective in controlling headache and nerve pain. These are not sedating except in high doses, and don’t depress the respiratory cycle.

There are support groups and medical facilities set up to help people cope with chronic pain. Ring your local doctor or call Synapse on 1800 673 074 for further information.
