Migraines
A migraine is caused by a chemical imbalance in your body. If there is a high amount of a certain chemical flowing through your body your blood veins will shrink, and will not cause you any pain. If your body is lacking a certain chemical or has a low amount of chemical in the body then your blood veins will swell, causing pressure to build up that can be very painful. This is when you know you have a migraine.
There are many things that can cause a migraine. Light, sound, smells, and foods are just a few things that can trigger a migraine. The only clue your body can give you that you are about have a migraine is through abnormal weakness, being depressed, or sometimes having a sudden burst of abnormal energy.
You should take a migraine seriously because it could lead to serious illness and physical problems such as side vision loss or color blindness.
If you get reoccurring migraines you should seek medical attention as soon as possible so that the problem can be resolved.
