A headache is pain or discomfort in the head, scalp, or neck. Serious causes of headaches are very rare. Most people with headaches can feel much better by making lifestyle changes, learning ways to relax, and sometimes by taking medications.
Pain - head; Rebound headaches; Medication overuse headaches
The most common headaches are likely caused by tight muscles in your shoulders, neck, scalp, and jaw. These are called tension headaches. They are often related to stress, depression, or anxiety.
Overworking, not getting enough sleep, missing meals, and using alcohol or street drugs can make you more likely to get them. Headaches can be triggered by:
People who drink caffeine can have headaches when they don't get their usual daily amount.
Other common causes include:
Tension headaches tend to be on both sides of your head. They often start at the back of your head and spread forward. The pain may feel dull or squeezing, like a tight band or vice. Your shoulders, neck, or jaw may feel tight and sore. The pain is usually persistent, but it does not get worse with activity.
Migraine headaches are severe headaches that usually occur with other symptoms such as vision disturbances or nausea. The pain may be described as throbbing, pounding, or pulsating. It tends to begin on one side of your head, although it may spread to both sides.
You may have an "aura" (a group of warning symptoms that start before your headache). The pain usually gets worse as you try to move around. For more information on this type of headache, see: Migraine.
Other types of headaches:
Headaches may occur if you have a cold, the flu, fever, or premenstrual syndrome.
If you are over age 50 and are getting headaches for the first time, a condition called temporal arteritis may be the cause. Symptoms of this condition include vision problems and pain that gets worse when you chew. There is a risk of becoming blind with this condition, so you should get treatment right away.
Rare causes of headache include:
Keep a headache diary to help find the source or trigger of your symptoms. Then change your environment or habits to avoid future headaches.
When a headache occurs, write down:
After a period of time, you may begin to see a pattern.
You may relieve a headache by resting with your eyes closed and head supported. Relaxation techniques can help. A massage or heat applied to the back of the upper neck can help relieve tension headaches.
TAKING HEADACHE MEDICATIONS AT HOME
Try acetaminophen, aspirin, or ibuprofen for tension headaches. Do NOT give aspirin to children because of the risk of Reye syndrome.
Migraine headaches may respond to nonsteroidal anti-inflammatory drugs (NSAIDs), or migraine medications that contain a combination of drugs.
If over-the-counter remedies do not control your pain, talk to your doctor about possible prescription medications.
People who take pain medications regularly for 3 or more days a week may develop medication overuse, or rebound headaches. All types of pain pills (including over-the-counter drugs) can cause rebound headaches. If you think this may be a problem for you, talk to your health care provider.
Prescription medications used for migraine headaches include:
Sometimes medications to relieve nausea and vomiting are helpful for other migraine symptoms.
If you get headaches often, your doctor may prescribe medication to prevent headaches before they occur. It is important to take these medicines every day as prescribed, even when you are not having a headache.
Take the following symptoms seriously. If you cannot see your health care provider right away, go to the emergency room or call 911 if:
See your health care provider soon if:
Your health care provider will take a medical history and will perform an examination of your head, eyes, ears, nose, throat, neck, and nervous system.
The diagnosis is usually based on your history of symptoms. A "headache diary" may be helpful for recording information about headaches over a period of time. Your doctor may ask questions such as:
Diagnostic tests that may be performed include the following:
If a migraine is diagnosed, you may be prescribed medications that contain ergot. Temporal arteritis must be treated with steroids to help prevent blindness. Other disorders are treated as appropriate.
