Either type of headache may convert to the other type. CausesThe cause of cluster headaches is not known. It is thought that there is abnormal activation of the area of the brain that is responsible for regulating temperature, blood pressure, hormone release, and sleep. The pain is thought to be caused by a combination of widening of the blood vessels and inflammation of the nerves of the face. Other possible causes include:

MedicationDrugs used to treat migraines often relieve sudden attacks of cluster headaches. These drugs must be taken at the first sign of a headache. Drugs used to treat cluster headaches include:
In some cases, the headache does not last long enough for drugs to be helpful. Sometimes, the drugs just delay an attack, rather than stop an attack. Pain killers, especially narcotic drugs, should not be used during an acute attack. Other medicines may be given to prevent or reduce the frequency of headaches. Examples of these drugs include:
Oxygen TherapyBreathing 100% oxygen for 10-15 minutes often relieves cluster headache pain. This is often viewed as the front-line therapy for cluster headache. The oxygen appears to decrease blood flow to the affected area of the brain. People under age 50 who have episodic cluster headaches seem to benefit most from oxygen therapy. Oxygen therapy can be expensive, and there are risks with this therapy. SurgeryAs a last resort, some doctors may recommend cutting or destroying a facial nerve to eliminate pain. PreventionTo prevent cluster headaches from getting worse, preventive medicine may be given. In addition:
