Abstract
While one therapy is generally ineffective for neuropathic pain, a multidisciplinary treatment is likely to be effective. Various treatments such as a nerve block, minimally invasive surgery, rehabilitation and psychotherapy are necessary, along with pharmacotherapy. Some conditions require opioid prescriptions for patients with chronic pain. Analgesic effects are insufficient with other treatments. A doctor-patient relationship must be established in those not having a psychiatric disorder or drug dependency. After fixing the dosage, it should not be readily increased. It is expected that the chronic pain patient will continue taking opioids throughout life. Therefore, the patients receiving this treatment should be carefully selected.
