It is thought that between a third and half of UK adults (just under 28 million of us) are affected by chronic pain.
Statistics indicate that women (38 per cent) are more affected than men (30 per cent) and unsurprisingly, prevalence increases with age, ranging from 16 per cent among people aged 16-24 to 53 per cent among those aged 75 years and older.
Since the three most common types of pain are back pain (reported by 53 per cent of people), headache (48 per cent), and joint pain (46 per cent), it’s likely that pharmacy teams will have daily interactions with customers experiencing chronic pain – so what exactly is it, why does it happen, and what can help?
The cause
Pain is deemed to be chronic when it persists or recurs for more than three months and is an unpleasant sensory and emotional experience associated with “actual or potential tissue damage”, according to the National Institute of Health and Care Excellence (NICE). Chronic primary pain persists for longer than three months and is associated with significant emotional distress or functional disability that cannot be explained by another chronic condition.
Chronic pain is “multifactorial” – meaning that biological, psychological, and social factors contribute to the pain syndrome – and there are many possible causes, such as an acute injury like a fracture; surgery or medical interventions; an ongoing degenerative illness or musculoskeletal condition such as osteoarthritis, rheumatoid arthritis or ankylosing spondylitis; conditions such as cancer, angina, irritable bowel syndrome (IBS) or chronic obstructive pulmonary disease (COPD); as well as headache from medicines overuse, or migraine; and even psychological causes, including anxiety, depression and sleep disturbances.
Treatment options
Although analgesics can sometimes work effectively to relieve chronic pain, data from NICE says this is only achieved in a small percentage of people, and it is unusual for any analgesic, including strong pain relief such as opioids, to completely eliminate chronic pain.
As a result, non-pharmacological treatment may be more effective at reducing symptoms and disability in some people experiencing chronic pain and can also augment and complement analgesic use.
NICE recommends that everyone with chronic primary pain is encouraged to remain physically active for longer-term general health benefits, so pharmacy teams can recommend people ask their GP – or local social prescriber – for a referral to a supervised group exercise programme, as well as referral to a specialist pain centre if appropriate.
Acceptance and commitment therapy (ACT) or cognitive behavioural therapy (CBT) can also help, and the person’s GP will also be able to talk them through the benefits and risks of considering an antidepressant – either amitriptyline, citalopram, duloxetine, fluoxetine, paroxetine, or sertraline for people aged 18 years and over – as these may be used off-label to help with quality of life, pain, sleep, and psychological distress, even in the absence of a diagnosis of depression.
Although not recommended for chronic pain, there are some useful gadgets out there which may provide relief from acute pain, as well as recovery from sporting injuries.
