Chronic pain does not go away by itself and
can last the rest of someone’s life. Many conditions or diseases, such as
arthritis, back pain (not the result of recent surgery), and cancer can cause
chronic pain. In some cases, the cause of the pain is not known, and needs to
be investigated by a doctor.
Chronic pain can be mild, moderate or
severe, as can acute pain. Chronic pain can cause reduced mobility or
depression, to name but two possible long-term effects.
There are many different types of
painkillers that can be used to relieve both acute and chronic pain. The object
of all of them is to return the body to a pain-free, or less painful state, and
to improve the general functioning of the patient.
