Migraine without aura

Migraine without aura is a common type of headache that causes intense, throbbing pain, usually on one side of the head. It can be accompanied by symptoms such as nausea, vomiting, and sensitivity to light and sound. Unlike migraine with aura, this type does not involve visual or sensory disturbances before the headache starts. Triggers can include stress, certain foods, hormonal changes, and lack of sleep. Attacks can last from a few hours to several days, and while the exact cause is not fully understood, it is believed to involve changes in brain activity and blood flow.
