About Pain Medicine
What is Pain Medicine?
Pain Medicine covers the treatment of people suffering from acute (under 3 months in duration) or chronic (over 3 months in duration) pain.
What is chronic pain?
Chronic pain is a persistent pain, which continues after healing or is the result of ongoing damage and includes spinal pain, post-traumatic pain (e.g. after amputation or surgery), pain involving the central or peripheral nervous system (e.g. post stroke pain, complex regional pain syndrome, diabetic neuropathy, post herpetic neuralgia and sciatica) and pain associated with other chronic diseases such as angina, arthritis, endometriosis, headache and pancreatitis. This includes cancer pain, which encompasses any pain in patients with cancer that is caused by the cancer or associated with the treatment.
Chronic Pain is also recognised as a Long Term Condition in its own right. Of all chronic diseases, pain related conditions had the biggest impact on quality of life – more so than cancer, chronic respiratory diseases and visual impairments.
What is acute pain?
Acute pain (also known as inpatient pain) relates to pain occurring during tissue damage and repair for example during sudden illness, surgery, trauma and burns. The pain typically improves with tissue healing.

Who are Pain Medicine Specialists?
A Pain Medicine Specialist is a doctor with specialist qualifications who undertakes the comprehensive assessment and management of acute, chronic and cancer pain in adult and paediatric patients, usually working within a multidisciplinary team. Most Pain Medicine Specialists are hospital based, though some work as specialists in the community or other health care settings.
Whilst most patients with pain can be managed in the primary or community sectors, some patients will need the involvement of specialists to manage their care.
