Acute pain is a normal physiological response to an unwanted and adverse chemical, mechanical or heat related trigger after surgery, trauma or any acute illness. Acute pain results from activation of the pain receptors (nociceptors) at the site of tissue damage. This type of pain is expected after surgery and anywhere where tissue damage occurs or inflammatory processes happen. Acute pain plays the important role of providing a warning signal that something is wrong and in need of further examination. Acute pain is typically self-limited and resolves over days to weeks, but it can persist for 3 months or longer as healing occurs. Acute pain can produce responses such as high BP, increased heart rate, sweating, shallow respiration, restlessness, facial grimacing, guarding behaviour and pupil dilation. Inadequate relief of acute pain can contribute to impaired immunity, leading to such complications as DVT and infections. Inadequately controlled acute pain can be a factor in the development of chronic pain, extended hospital stay, readmission, and patient dissatisfaction. In hospital, acute pain is managed by the acute pain team usually led by a consultant pain specialist and specialist pain nurses. Often a wide variety of pain relief interventions are started by anaesthetists in theatre and these may be, Spinals, Epidurals, nerve blocks and Patient controlled analgesia of strong opioids such as morphine and oxycodone and fentanyl.
Pain is considered chronic when it has persisted beyond 3 months since onset. Often we expect acute pain to resolve by this time but the mechanisms for acute pain do not switch off for many reasons. There is a significant societal burden and impact because of chronic pain and quite rightly, the Department of Health has recognised that chronic pain is a long term condition in its own right and a chronic disease in itself that must be recognised early and managed appropriately. The Chief Medical Officer’s report states that 25% of pain patients lose their jobs. 5 of the top 12 disabling conditions globally are persistent pain conditions and low back pain is ranked highest out of 291 conditions for years lost to disability.
Managing chronic (persistent) pain
Chronic pain can feel like a lonely experience but in fact, it affects fourteen million people in the UK. Yet many people suffer needlessly, and could find relief through modern pain management treatments and a holistic approach that considers mind and body alike. This philosophy of treating the whole person is vital, as persistent pain has a profound impact on both physical and mental wellbeing, and on your near and dear ones. Quite often, people with chronic pain are referred from one specialist doctor to another for a number of years without a proper diagnosis, adequate treatment or explanation. If this sounds like you – or one of your patients – we can help. We start with a thorough and comprehensive evaluation to determine the cause of the pain and its effect on everyday life. The next step is to agree a treatment plan, so there are defined goals and everyone knows what to expect along the way. In line with best practice, we adopt an evidence based, multidisciplinary approach to managing and treating various pain conditions. This may include a judicious combination of medication, injection therapy, exercise and psychological support where necessary. We strongly believe that knowledge helps people manage their pain better. Our goal is to put our patients in the driver’s seat, allowing them to manage the pain and return to an active and enjoyable life. We provide a wide variety of therapies such as Acupuncture, Pain Management Programmes, Pacing and Mindfulness strategies, MDT consultations and other injection therapies
