Effective pain management requires appropriate patient assessment, ongoing reassessment, and an understanding of the options available for the treatment of patients with chronic pain. Opioids have long been an important option in the management of moderate to severe chronic pain, but optimal use requires understanding the variety of choices currently available. ⋯ Long-term clinical trials of these formulations are needed to allow clinicians to make informed decisions about which patient groups might benefit most from these formulations.

Review
Evidence-based interventional pain medicine according to clinical diagnoses. 2. Cluster headache.
Cluster headache is a strictly unilateral headache that is associated with ipsilateral cranial autonomic symptoms and usually has a circadian and circannual pattern. Prevalence is estimated at 0.5 to 1.0/1,000. The diagnosis of cluster headache is made based on the patient's case history. ⋯ In conclusion, the primary treatment is medication. Radiofrequency treatment of the ganglion pterygopalatinum should be considered in patients who are resistant to conservative pain therapy. In patients with cluster headache refractory to all other treatments, occipital nerve stimulation may be considered, preferably within the context of a clinical study.
