In addition to severe headache pain, migraines are often accompanied by other symptoms. Nausea is a very common occurrence. A person with a migraine headache often becomes overly sensitive to light and sound and may go to a dark, quiet room to avoid these things. Fatigue, weakness and appetite loss are also common with a migraine. A person with a migraine may have trouble concentrating on anything because of the pain.
Some people who get migraines experience symptoms before the headache itself starts. These warning symptoms are referred to as a migraine aura. The aura, if it is noticeable, usually occurs immediately before the headache, approximately 15 minutes before the pain starts. Some people with migraines do not notice an aura at all. However, some people with migraines experience aura symptoms several hours before the headache begins. These aura symptoms are typically disturbances of vision, such as difficulty focusing the eyes that leads to blurred vision, tunnel vision, blind spots and flashes of light. Light sensitivity and eye strain can occur before the onset of migraine pain. Some people also experience nausea and inability to concentrate before the headache sets in.
Migraines can be triggered or influenced by certain things, such as hormonal changes, alcohol consumption and stress, but sometimes the cause of migraine headaches is unknown.
