The nerve which affects the trigeminal nerve is responsible for feeling heat or ache in the face. It’s around your eye, and its branches up to the forehead, all over the cheek, below the jawline, and above your ear.
An underlying brain condition, for example, a tumor or aneurysm is not responsible for cluster headaches.

Cluster Headaches Treatments:

There is no complete cure for cluster headaches, but medications, for example, sumatriptan, and other cures, including oxygen therapy, can decrease the occurrence and harshness of cluster headaches.
The purposes of the treatments are to get rid of some of the symptoms, decrease the period of headaches, and their incidence.
Over-the-counter (OTC) pain reliever, for example, ibuprofen or aspirin is not useful, because the pain starts and finishes very fast that by the time the effect of medicine in the body begins to work, the headache has possibly gone.
Medicines and treatments for cluster headaches aim either to stop them or to turn rapidly.

Breathing oxygen: Inhaling 100 percent oxygen by a mask at 7 to 10 liters in every minute may bring an effective relief by 15 minutes. You will not need to carry an oxygen cylinder and regulator always, some small elements are available.
Injectable sumatriptan (Imitrex): Triptans can give relief migraines. Sumatriptan works as an agonist for 5-hydroxytryptamine (5-HT) sense organ. It can relieve migraines and provide quick relief from cluster headaches. 
Zolmitriptan (Zomig) is a type of nasal spray, however it only useful for some patients. The adult patient’s dosage is a 6-milligram injection. Two injections can be pushed within 24-hours.
People with high blood pressure or ischemic heart disease should not take this medication.
Dihydroergotamine: This is useful pain relief for a few persons. It can be taken through the vein or breathe in. First of all, a medical expert thinks about giving an intravenous dosage. The inhaling process is useful but slow acting.
Octreotide (Sandostatin, Sandostatin LAR): These are artificial forms of somatostatin, a brain hormone. It is pushed through injection. It is a useful treating option for cluster headaches and regarded as safe for people with high blood pressure or ischemic heart disease.

Preventive Treatments for Cluster Headaches:

People with cluster headaches take short or long-term treatments. If the cluster period is over, the short-term treatments stop; however, the long-term treatments may carry on.
If cluster attacks occur often or last over three weeks, preventive treatments are suggested. The person will take the treatments before starting headaches, and last until the headaches periods end up.

Short-Term Medications for Cluster Headaches:

Corticosteroids: These steroids, such as Prednisone, suppress inflammation. They are rapid-acting protective medicine that works well for the people with new symptoms or those who have long term remission and short term cluster.
Ergotamine (Ergomar): This is a short term narrowing blood vessels in the body. It is applied before going to bed at night, through placing under the tongue or as a rectal suppository. Ergotamine should not be taken with triptans as well as should not be taken for a long time, or a person who has poor circulation.
Anesthetic on the occipital Nerve: Taking anesthetic injection at the back of the head can numb this nerve. Accordingly, pain messages that travel along the nerve pathway are blocked. This treatment should stop as soon as possible, and a long-term preventative medication should start.

Long-Term Medications for Cluster Headaches:

Long-term medications are taken during the cluster period. A number of persons may require long-term treatment.
Calcium channel blockers, for example, verapamil (Verelan, Calan): These are taken at the period of cluster headaches and then slowly tapered off, although some people may require using them a longer period of time. Some side effects of using channel blockers are constipation, nausea, exhaustion, puffy ankles, low blood pressure, and vertigo. If the dosage is increased, regular heart checking will be required.
Lithium carbonate, such as, lithium (Eskalith, Lithobid): these are applied to treat bipolar disorder; it is also useful for stopping chronic cluster headaches. Some Side effects for using these medications are diarrhea, urination, and tremor. The amount of side effects is usually related to dose, which the doctor can change. Blood tests will be checked regularly for possible kidney damage.
