Migraine Headaches
Symptoms
Migraine headache symptoms vary and may occur with or without a warning sign called an aura. People who get an aura, which usually begins within 30 minutes before the headache starts, may see spots, wavy lines, or flashing lights. Some people have numbness or a "pins-and-needles" sensation in their hands, arms, or face during the aura. However, most people do not have an aura before they get a migraine headache.
Common symptoms of migraine include:
- Throbbing or pulsating headache on one side of your head.
- Moderate to severe headache intensity.
- Your headache getting worse with routine physical activity.
- Nausea, vomiting, or both.
- Sensitivity to light and noise, and sometimes smells.
There are several types of migraine headaches, each with unique features. For example, some women get migraines before, during, or shortly after their menstrual period.
It can be difficult to distinguish migraines from other types of headaches. Sinus or tension headaches have symptoms similar to those of migraines. Unlike other headaches, however, migraines usually occur on one side of your head, although the side that is affected can shift with each new attack. Migraines are also often accompanied by sensitivity to light and noise.
Migraines may occur along with many other conditions such as asthma or depression.3 More serious conditions, such as tumours or infections, can also cause migraine-like symptoms. Headaches that are caused by more serious health problems are rare.
