Silent migraines causes confusion in the medical community, because they come without the pain of a headache. Instead, they usually come with a host of other symptoms, including eye disturbances. Unfortunately with silent migraines, the symptoms are unpredictable. There are four main phases of silent migraines.
The prodrome is the precursor to a migraine. You may experience a change in mood (i.e. irritability), confusion, thirst or diarrhoea.
Many silent migraines are accompanied by visual disturbances, such as auras, wavy lines, spots, hallucinations or flashing lights.
Silent migraines are not typically associated with head pain. Sometimes localised pain on one side of the head can be experienced, as well as nausea and vomiting.
Silent migraines can last for up to seventy-two hours. Once they are over, many sufferers experience fatigue.
Physical symptoms of silent migraines include flu-like symptoms (fever and vomiting), joint pain, slurred speech, itching and rashes, loss of appetite, increased urination, fatigue or numbness in the body.
People may also experience speech difficulties, smell or taste disturbances, a feeling of numbness, or the sensation of the hands or legs going to sleep.
