Your caregiver will ask about your medical history and examine you. You may need any of the following tests:
- Neurologic exam: Your caregiver will check how your pupils react to light. He may check your memory and your hand grasp and balance.
- CT scan: An x-ray uses a computer to take pictures of your brain. You may be given dye before the pictures are taken to help caregivers see the pictures better. Tell caregivers if you are allergic to iodine or shellfish. You may also be allergic to the dye.
- MRI: This scan uses powerful magnets and a computer to take pictures of your head and blood vessels. You may be given dye to help the pictures show up better. Tell caregivers if you are allergic to iodine or shellfish. You may also be allergic to the dye. Do not enter the MRI room with anything metal. Metal can cause serious injury. Tell caregivers if you have any metal in or on your body.
How is a migraine headache treated?
There is no cure for migraines. The goal of treatment is to reduce your symptoms. Take medicine as soon as you feel a migraine begin.
- Pain medicine: You may need medicine to take away or decrease pain. You may need a doctor's order for this medicine. Do not wait until the pain is severe before you take your medicine.
- Migraine medicines: These are used to help prevent a migraine or stop it once it starts.
- Antinausea medicine: This medicine may be given to calm your stomach and to help prevent vomiting. They can also help relieve pain.
How can I manage my symptoms?
- Rest: Rest in a dark, quiet room. This will help decrease your pain.
- Ice: Ice helps decrease pain. Use an ice pack or put crushed ice in a plastic bag. Cover the ice pack with a towel and place it on your head where it hurts for 15 to 20 minutes every hour.
- Heat: Heat helps decrease pain and muscle spasms. Use a small towel dampened with warm water or a heating pad, or sit in a warm bath. Apply heat on the area for 20 to 30 minutes every 2 hours. You may alternate heat and ice.
How can I prevent another migraine headache?
- Keep a headache diary: Write down when your migraines start and stop. Include your symptoms and what you were doing when a migraine began. Record what you ate or drank for 24 hours before the migraine started. Describe the pain and where it hurts. Keep track of what you did to treat your migraine and whether it worked. Bring this log with you each time you see your caregiver.
- Do not smoke: If you smoke, it is never too late to quit. Tobacco smoke can trigger a migraine. It can also cause heart disease, lung disease, cancer, and other health problems. Quitting smoking will improve your health and the health of those around you. If you smoke, ask for information about how to stop.
- Do not drink alcohol: Alcohol can trigger a migraine. It can also interfere with the medicines used to treat your migraine.
- Get regular exercise: Exercise may help prevent migraines. Talk to your caregiver about the best exercise plan for you.
- Manage stress: Stress may trigger a migraine. Learn new ways to relax, such as deep breathing.
- Stick to a sleep schedule: Go to bed and get up at the same time each day.
- Eat regular meals: Include healthy foods such as fruit, vegetables, whole-grain breads, low-fat dairy products, beans, lean meat, and fish. Avoid trigger foods like chocolate, hard cheese, and red wine. Foods that contain gluten, nitrates, MSG, or artificial sweeteners may also trigger migraines. Caffeine, which is often used to treat migraines, can also trigger them.
