Migraine

ABSTRACT: The results of diagnostic tests do not correlate well with the presence and severity of pain. To avoid missing a serious underlying condition, look for "red flags," such as unexplained weight loss or acute bladder or bowel function changes in a patient with low back pain. Nonopioid medications can be more effective than opioids for certain types of pain (for example, antidepressants or anticonvulsants for neuropathic pain). When NSAIDs are indicated, cyclooxygenase-2 inhibitors are better choices for patients who are at risk for GI problems or who are receiving anticoagulants. However, if nonspecific NSAIDs are not contraindicated, consider using these far less expensive agents. The tricyclic antidepressants are more effective as analgesics than selective serotonin reuptake inhibitors. When opioids are indicated, start with less potent agents (tramadol, codeine, oxycodone, hydrocodone) and then progress to stronger ones (hydromorphone, fentanyl, methadone, morphine) if needed.

The patient is a 56-year-old man who presents with daily headaches that occurbehind the right eye, right temple, and occasionally on the right side of theforehead. He has never experienced this type of headache on the left side. Hedescribes the pain as “stabbing,” “throbbing,” and occasionally “burning.”He rates the intensity of the pain a 7 on a 10-point visual analog scale onwhich 10 is the most severe.

Many patients who present to the emergency department(ED) with severe headache request a narcotic to relieve thepain.

You recently diagnosed migraine without aura in a patient who complains of headaches of moderate intensity. Is a migraine-specific prescription agent warranted?

A 34-year-old woman complains of headaches that interfere with work. Her first headache episode, approximately 6 yearsearlier, was relatively mild. Initially, she experienced attacks only once every 3 to 4 months and managed them effectivelywith over-the-counter (OTC) agents. However, in the last 6 months the attacks have become more frequent-they occur atleast twice a month-and are so severe that she misses work.

ABSTRACT: Systematic palpation can detect a trigger point; often, muscle spasms or a nodule will be present. Injection of the trigger point with a local anesthetic usually reduces pain promptly; the procedure can also effect long-term pain relief and increased range of motion. However, pain may recur and even worsen 1 to 3 days after an injection-either because additional injections are needed or because the trigger point was not completely injected. To maintain pain relief and improve strength and range of motion in the affected muscle following injection, recommend stretching exercises, physical or massage therapy, or rest. Trigger point injections can be associated with adverse effects (eg, temporary numbness, injection site irritation, and dizziness); complications include vasovagal syncope, skin infection, and compartment syndrome.

Calcium channel blockersare commonly prescribedto treat severalcardiovascular diseasesand may be helpful inother conditions, such as migraineand bipolar disorder.1 These agentsare associated with numerous clinicallysignificant drug interactions.1-3While some of these interactions,such as the effect of verapamil onserum digoxin concentrations, arewell-known, others are not widely recognized-yet warrant attention.

ABSTRACT: A thorough history and physical examination can establish the diagnosis of tension headache; further evaluation is generally unnecessary. In contrast, the workup of cervicogenic headache includes standard radiographs, 3-dimensional CT, MRI, and possibly electromyography; nerve blocks may also be used to confirm the diagnosis. Episodic tension headache can be treated effectively by trigger avoidance, behavioral modalities, and structured use of analgesics. Reserve opioids for patients with intractable headaches. Chronic tension headache is treated primarily by prophylactic measures, such as antidepressants and anticonvulsants, and behavioral and physical therapy. Treatment options for cervicogenic headache include analgesics; invasive procedures, such as trigger point injections, greater or lesser occipital nerve blocks, facet joint blocks, segmental nerve root blocks, and diskography; spinal manipulation; and behavioral approaches.

Anisocoria and partial eyelid ptosis were detected during the routine eye examination of a 66-year-old woman. These findings had not been present during an examination 2 years earlier. Because the patient had no symptoms, she could not recall when these signs began. Her general health was unremarkable; she had smoked 1 pack of cigarettes per day for 40 years

A bright, active 10-year-old boy has been experiencing recurrent bouts ofabdominal pain with nausea and occasional vomiting for 3 years. Although hehas had 1 or 2 attacks at school, the pain usually occurs at home-frequentlyon weekends. His mother has been unable to correlate these episodes with particularfoods or activities. She notes that her son has experienced motion sicknessduring long auto trips and during a family holiday in the mountains ofColorado.

A 37-year-old woman presents to the emergency departmentwith a diffuse, sharp, pounding headache,which started 2 hours earlier. She rates her discomfort as4 on a scale of 1 to 10. Neck muscle soreness is also present,but the pain does not radiate.

Three strategies have commonly been used for episodic migraine. In step care across attacks, the least expensive medications are tried for several episodes. If these fail, treatment is "stepped up" to specific agents.

Migraine is an episodic, often debilitatingcondition that affects women moreoften than men. Twenty-eight millionAmericans suffer from migraineheadaches-and nearly 75% of theseare women.1 Unlike other chronic painconditions, migraine has its peakprevalence during the years of greatestproductivity, when most women arejuggling family responsibilities andcareers.2 Many women are particularlysusceptible to migraine attacks justbefore and during menses.
