Pain can begin for many reasons and can continue for months, in some cases for life.
Sometimes investigations will find no cause for the pain; however usually the cause is known but the pain may be difficult to manage, for example sciatica, neuropathic pain of diabetic neuropathy, and cancer pain.
In these situations pain is best managed by consultants with a special interest and training in pain management, usually a consultant anaesthetist. Pain management may be achieved with drugs or using interventional procedures such as joint injections, nerve blocks, epidurals etc.
Sometimes patients may benefit from the input of a physiotherapist, psychologist or other professional.
