There are four different phases of migraines. You may not always go through every phase each time you have a migraine.:
Migraines are more common in the morning; people often wake up with them. Some people have migraines at predictable times, such as before menstruation or on weekends following a stressful week of work.
How are migraines diagnosed?To make a diagnosis, your health care provider will:
An important part of diagnosing migraines is to rule out other medical conditions which could be causing the symptoms. So you may also have blood tests, an MRI or CT scan, or other tests.
How are migraines treated?There is no cure for migraines. Treatment focuses on relieving symptoms and preventing additional attacks.

Almost everyone has had a headache. Headache is the most common form of pain. It's a major reason people miss days at work or school or visit the doctor.
The most common type of headache is a tension headache. Tension headaches are due to tight muscles in your shoulders, neck, scalp and jaw. They are often related to stress, depression or anxiety. You are more likely to get tension headaches if you work too much, don't get enough sleep, miss meals, or use alcohol.
Other common types of headaches include migraines, cluster headaches, and sinus headaches. Most people can feel much better by making lifestyle changes, learning ways to relax and taking pain relievers.
Not all headaches require a doctor's attention. But sometimes headaches warn of a more serious disorder. Let your health care provider know if you have sudden, severe headaches. Get medical help right away if you have a headache after a blow to your head, or if you have a headache along with a stiff neck, fever, confusion, loss of consciousness, or pain in the eye or ear.

Caffeine is a bitter substance that occurs naturally in more than 60 plants including:
There is also synthetic (man-made) caffeine, which is added to some medicines, foods, and drinks. For example, some pain relievers, cold medicines, and over-the-counter medicines for alertness contain synthetic caffeine. So do energy drinks and "energy-boosting" gums and snacks.
Most people consume caffeine from drinks. The amount of caffeine in different drinks can vary a lot, but it is generally:
Caffeine has many effects on your body's metabolism. It:
Within one hour of eating or drinking caffeine, it reaches its peak level in your blood. You may continue to feel the effects of caffeine for four to six hours.
What are the side effects from too much caffeine?For most people, it is not harmful to consume up to 400mg of caffeine a day. If you do eat or drink too much caffeine, it can cause health problems, such as:
Some people are more sensitive to the effects of caffeine than others.
What are energy drinks, and why can they be a problem?Energy drinks are beverages that have added caffeine. The amount of caffeine in energy drinks can vary widely, and sometimes the labels on the drinks do not give you the actual amount of caffeine in them. Energy drinks may also contain sugars, vitamins, herbs, and supplements.
Companies that make energy drinks claim that the drinks can increase alertness and improve physical and mental performance. This has helped make the drinks popular with American teens and young adults. There's limited data showing that energy drinks might temporarily improve alertness and physical endurance. There is not enough evidence to show that they enhance strength or power. But what we do know is that energy drinks can be dangerous because they have large amounts of caffeine. And since they have lots of sugar, they can contribute to weight gain and worsen diabetes.
Sometimes young people mix their energy drinks with alcohol. It is dangerous to combine alcohol and caffeine. Caffeine can interfere with your ability to recognize how drunk you are, which can lead you to drink more. This also makes you more likely to make bad decisions.
Who should avoid or limit caffeine?You should check with your health care provider about whether you should limit or avoid caffeine if you:
If you have been consuming caffeine on a regular basis and then suddenly stop, you may have caffeine withdrawal. Symptoms can include:
These symptoms usually go away after a couple of days.
When you're dizzy, you may feel lightheaded, woozy, or disoriented. If you feel like you or the room are spinning, you have vertigo. These feelings may make you lose your balance.
Dizziness can have many different causes. A sudden drop in blood pressure or being dehydrated can make you dizzy. Many people feel lightheaded if they get up too quickly from sitting or lying down. Certain medicines and problems with your inner ear may cause dizziness. So can motion sickness. Sometimes dizziness can be a symptom of other disorders.
As people get older, they may have more health problems and take more medicines. This makes them more likely to have problems with dizziness and balance.
Dizziness usually gets better by itself or is easily treated. If you are dizzy often, you should see your health care provider to find the cause.

Antidepressants are prescription medicines to treat depression. Depression is more than feeling a little sad or "blue" for a few days. It's a very common, serious medical illness that affects your mood and general mental health It can make you feel tired, hopeless, worried, or fearful. It can change your thinking, sleeping, and eating. Depression may make some people think about ending their lives.
But antidepressants can help many people who have depression. Researchers think antidepressants may help improve the way your brain uses certain chemicals that control mood or stress.
Are antidepressants used for other conditions?A health care provider may prescribe antidepressants for anxiety, chronic pain, or insomnia. Sometimes providers also prescribe antidepressants for other conditions.
What are the different types of antidepressants?There are many types of antidepressants. Each one works differently. Providers usually prescribe newer antidepressants first because they don't cause as many side effects as older types. They also seem to help more kinds of depression and anxiety problems.
Most of the newer antidepressants belong to one of these three groups:
If these antidepressants don't help, your provider might suggest one of the older antidepressants. The older types include tricyclic antidepressants (TCAs), tetracyclics, and monoamine oxidase inhibitors (MAOIs). Even though these antidepressants may cause more serious side effects, the benefits may outweigh the risks for some people.
Which type of antidepressant is right for me?Our bodies and brains all work differently. That means one antidepressant won't work for everyone. You may need to try two or more medicines before you find one that works for you.
Your provider will work with you to choose the best option to try first. You'll consider questions such as:
Antidepressants usually take 4 to 8 weeks to work, so you'll need to be patient. You may notice that some problems, such as sleeping and eating, get better before your mood improves. That's a good sign. You may just need to give the medicine a little more time to do its job.
Sometimes an antidepressant helps at first, but symptoms return while you're still taking it. But there's usually another one you can try. To get more relief from depression, your provider may suggest combining two antidepressants, using another kind of medicine with an antidepressant, or adding talk therapy or other approaches to improve your mental health.
How long will I need to take an antidepressant?When an antidepressant starts to work, you and your provider can decide how long you need to stay on it. The typical length of treatment is 6 to 12 months, but some people may stay on antidepressants for much longer.
What are the side effects of antidepressants?Not everyone has side effects from antidepressants. But if you do have them, they're usually mild and may get better over time as your body gets used to the new medicine.
The most common side effects from antidepressants include:
When thinking about side effects, it's important to remember that there are also risks from not treating depression. Your provider can help you think through the pros and cons of all your options.
If you have any side effects from antidepressants, your provider may suggest ways to manage them while you wait to see if the antidepressant will work. If the side effects bother you too much, you may need to change antidepressants. But you should never change your dose or stop taking an antidepressant on your own.
If you have serious problems or notice any changes that worry you, such as new or worsening symptoms, unusual changes in your mood, or you start acting differently, call your provider right away.
In some cases, children, teenagers, and young adults under 25 may be more likely to think about hurting or killing themselves when starting antidepressants or when the dose is changed. Get medical help right away if this happens.
What can I do to take antidepressants safely?Antidepressants are generally safe when you use them correctly:

Fibromyalgia is chronic (long-lasting) condition that causes pain all over the body, fatigue, and other symptoms. There is no cure, but treatments can help with the symptoms.
What causes fibromyalgia?The exact cause of fibromyalgia is unknown. Studies of the brains of people with fibromyalgia found that they seem to process pain differently than people who don't have it. They may feel pain when others do not, and they may also have a more severe reaction to pain.

And the main symptoms, pain and fatigue, are common in many other conditions. Providers have to rule out other causes of the symptoms before making a diagnosis of fibromyalgia. This is called making a differential diagnosis.
To find out if you have fibromyalgia, your provider:
Not all providers are familiar with fibromyalgia and its treatment. You should see a provider or team of providers who specialize in the treatment of fibromyalgia.
