They may be caused by changes in the brainstem and its interactions with the trigeminal nerve, which is a major pain pathway (Mayo Clinic, 2013). There are two major types of migraines: migraines without aura and migraines with aura (Migraine Again, 2010). None aura migraines, formerly known as common migraines, can occur without warning and usually contain the usual headache symptoms. Migraines with auras, formerly called classic migraines, may or may not occur with a headache and can strike at any time (Migraine Again, 2010).

Early warnings in this stage may include irritability, thirst, cravings, the need to sleep, or the frequent need to urinate (WebMD, 2014).

Changes in vision can occur such as seeing bright spots or an area of vision loss. Tingling or the “pins and needles” sensation in the body may occur in this phase and may also cause numbness. Sufferers may also have language problems such as trouble concentrating or understanding spoken or written words (WebMD, 2014). The third phase, the attack phase, is when the throbbing occurs. Normal activities are found to be difficult during this time and the person would usually seek rest, possibly away from light, sounds, and smells (WebMD, 2014). The last phase, the postdromal phase, occurs after the migraine. In this stage, the symptoms may include tiredness, sluggishness, confusion, and
